The five Tests India and England played in the summer of 2025 went the entire distance. Every match reached the fifth day. The series finished 2-2, with one draw, and three of the five results were decided by margins under 25 runs. Across the five matches, twenty-five days of cricket were played, and on every one of those days a result remained possible into the final session.

Nobody who watched that series will forget it. That is partly the cricket. It is also the format doing what the format is supposed to do.

Test matches that end in three days disappear from memory the moment the next series begins. The Tests that get etched into our memories are the ones that go five days. They finish in the final session and reward whichever side fought and persevered the most. India-England 2025 was watched because it was 2-2 across twenty-five days. The matches that go three days and 280 overs do not get watched the same way. They do not produce the moments cricket lives on.

This is not nostalgia. It is the architecture of the format.

Five days

No other team sport in the world asks its athletes to play across five continuous days. The format is unique not because it is long, but because the conditions change while you are playing them.

The red ball’s lifecycle dictates the Test match. It begins with the seamers’ dominance, transitions into a mid-innings containment phase as the ball softens, and resets with the second new ball at 80 overs. Factor in the onset of reverse swing and a pitch that evolves daily, and the format becomes four or five distinct games stitched together. All played by the same eleven people.

The weather rotates inside each day. Morning cloud assists swing, afternoon sun bakes the pitch and flattens it and late evening light brings the seamers back. Across five days, the team that bats and bowls in the session under helpful conditions can drive significant advantages that turn a stalemate into a decisive victory.

Across a series, bowlers fatigue. A fast bowler in the third Test of a tour has lost a yard. A spinner who bowled 60 overs in Test 1 has blisters by Test 2. Bodies break. The team that has driven the opposition’s fast bowlers into the ground by the second Test has often already won the third.

This is the variance canvas Test cricket plays across. Football is ninety minutes with substitutes. Basketball is forty-eight minutes with rotations. Baseball is nine innings with fresh pitchers. Only Test cricket asks its athletes to play continuously across five days, against changing conditions, with the same eleven people on either side

Test cricket is all about understanding when to attack and defend. It is the art of recognizing which sessions are for accumulating runs and which are for protecting the foundation, knowing that a single reckless hour can undo four days of patient, unglamorous labor.

The attritional cricketer

The attritional cricketer’s job description, properly written, would read: make the bowlers tired, make the ball old, make the pitch deteriorate, make the opposition’s plans degrade and survive long enough that someone else can convert all of this into runs.

They are not slow because they cannot score. They are slow because they are executing their role. A fast bowler bowling six balls at them for no runs has used six deliveries of his finite reserve. By the time the attritional cricketer has played out fifteen overs and the fast bowler is gone then the captain is bowling his fourth-choice option. By the time he has played out thirty, the second new ball is being taken against batters who have settled. By the time he has played out fifty, the pitch beneath him is no longer the pitch the openers walked out onto.

Pujara in Australia in 2018-19 is the modern apex of this archetype. Across four Tests he faced 1,259 balls which is 28.8% of every legal delivery India faced in the series. He played 999 dot balls. He averaged 74. The bowling unit he absorbed comprised of Cummins, Hazlewood, Starc and Lyon. They bowled 678 overs across that series as a group which is the heaviest workload they ever endured in any consecutive four-Test stretch of their careers. They would play 35 Tests together over seven years and win in every condition on earth. They never had to bowl more than they did at Pujara’s India.

Two years later, on the fifth morning at the Gabba with India chasing 328, he did it again. 56 off 211 balls. Five runs off Josh Hazlewood across forty-eight deliveries. Eleven blows to the body. While he endured, Shubman Gill made 91 and Rishabh Pant made 89 not out. Pant was named Man of the Match. India won the series.

He is the apex case of the recent times.

Alastair Cook in India in 2012-13 made 562 runs across four Tests at average 93.7 and strike rate 43.7, facing 1,285 balls against Pragyan Ojha and Ravichandran Ashwin on Indian pitches. England won 2-1. It was the first time England had won a Test series in India since 1985.

Usman Khawaja in Pakistan in March 2022 faced 995 balls across three Tests on subcontinental pitches at strike rate 49.8. Australia drew that series in Pakistan, the first time they had toured there in 24 years.

These players win nothing on their own. They are not the leading lights of their teams. They do not get the Man of the Match awards.

What the format rewards

It is tempting to read the modern era as the death of attritional cricket. Test averages have drifted down, strike rates have climbed up, and conventional wisdom says you cannot afford a player who scores at 45 SR in a format that now scores at 55 SR. The data partly supports this. Among top-7 batters in the modern era, those striking below 45 average just 31. The sweet spot is between 55 SR and 60 SR, where averages climb above 40.

But this reading is too quick. What modern cricket killed is pure attrition and not competent attrition. Batmen scoring at 42-48 SR while averaging above 40. Cook. Khawaja. Pujara. Azhar. Dravid. Rahul.

These players are now scarce, and their scarcity is visible in the touring data. When a touring side has a slow anchor who performs, their loss rate on tour is 49%. When the anchor fails, the loss rate climbs to 66%. The attritional cricketer is not in the business of generating wins. They are in the business of preventing collapses.

The fact that England phased out Cook with no successor is the cautionary tale. Their home win rate under Bazball is 65%. Their away record is 43%. They have not won an Ashes series in any form since the doctrine was adopted. They lost 1-4 in India in 2024. The team that most aggressively rejected the attritional role at home is the team paying for it abroad.

The test matches we remember

India played five Tests in England in the summer of 2025. KL Rahul opened, made 532 runs at average 44 and strike rate 47.6, faced 741 balls across nine innings. He did not win the series. He prevented the series from being lost. Twenty-five days of cricket. Nobody who watched it will forget it.

That is the format showing what it is for. The matches that get etched into cricket’s memory are the ones where attrition has worked from both ends and where both teams have someone willing to do the long, unglamorous work. Persevering for their side. Making sure the result is uncertain into the last session of the last day, where the bowlers running in have already bowled fifty overs in the match and are running in anyway because that is what Test cricket asks of them.

The three-day Tests do not produce these moments. A side bowled out for 180 on Day 1 and rolled again on Day 3 does not produce the cricket that gets remembered. What gets remembered is the partnership at 4 for 2 on Day 4 that survives into the evening session. The bowler in his 15th over of the inning finally finding reverse swing. The chase that goes deep into Day 5 with the result unresolved until the last session.

Every one of these moments has, somewhere in its construction, an attritional cricketer.

Cheteshwar Pujara took eleven blows to the body at the Gabba and did not flinch once. It was the last Test innings he ever played on Australian soil.

He was one of four in last 15 years. Dean Elgar opened for South Africa for a decade as the team’s anchor. Dimuth Karunaratne did the same job for Sri Lanka. Azhar Ali averaged forty-three at strike rate forty-two across a hundred Tests for Pakistan. They all played the same game Pujara played, and they all did it in the wrong era to be celebrated for it.

In any decade before this one, these four men would have had their flowers. Books, biographies, places in their countries’ cricketing pantheons assumed rather than contested. Instead they played their cricket inside the T20 era’s flamboyant power hitting. Their lineage was unmistakable. They came from the same school as Dravid, Boycott, Gavaskar, Atherton but the cricket conversation had moved on and the words it used for them were slow, defensive, dated.

The last attritional cricketer to receive his full due was Shivnarine Chanderpaul. He retired in 2015 with 11,867 Test runs at an average of 51.37, the seventh-highest run-getter in the history of the format. He was inducted into the ICC Hall of Fame in 2022. In my reckoning, he’s the last man of his school to walk off to the kind of applause his predecessors got. Celebrated in the same lineage as Tendulkar, Ponting, Kallis, Dravid, Sangakkara and Lara.

The role itself has not died. KL Rahul does it for India. Usman Khawaja did it for Australia. However, it seems like a dying art. The attritional cricketers make the match worth winning. No test team can be successful touring away without them. You can’t produce them without playing them at home.

The format will keep asking for them. The recognition, it seems, will not keep coming. The least we can do is notice.

Numbers in this piece are computed from Cricsheet ball-by-ball Test data, 2010-2025. “Slow anchor” is defined as a top-7 batter who faced at least 100 balls across a tour at a strike rate below 50; “performed” means the anchor averaged 35 or higher on the tour, “failed” means below 30. See the Methods & Sources page for the full methodology.

The bowler walks back to his mark for the twentieth over. Anything less than 12 runs needed off six is a formality with even 7 wickets down. Everyone in the ground already knows how this ends. The over becomes a formality. A piece of administrative tidying before the handshakes.

Final over used to be the most watched six balls in the sport. Now it is the bit you watch while you find your car keys. Contests have started to feel won before the 20th over.

So I went to check whether the feeling was true. I built the 20th Over Index to measure it. The definition is deliberately strict. A live final over is one where the result is still genuinely in doubt, the margin tight enough that one good ball or one bad one decides the match. Not a contrived finish. A real one.

The answer surprised me. Across the IPL’s whole history close to a third of all matches finish at the 20th over, and the long-run mark sits at around 32 percent. The recent dip is real. The last three seasons have all come in under 32 percent average mark, the softest three-year stretch the league has ever had. 2025 was the lowest single reading in over a decade. Close finishes have softened. They have not collapsed yet but they seem to be on a one-way trip down.

That should have been the end of the post. However, I looked at what had actually changed, and the shift was enormous.

The scoring has exploded. Run rate, first-innings totals, sixes, every one of them sits at an all-time high, and the climb is not gentle. The IPL ran at about eight runs an over for most of its life. In 2026 it ran at nearly ten. First innings used to settle around 165. In 2026 the average was almost 200. A side hit eleven sixes a match a decade ago. In 2026 it hit more than nineteen.

And the acceleration has a start date. The lines kick upward in 2023, which is the year the Impact Player rule arrived. That is not a coincidence dressed up as a finding. It is the finding.

What has collapsed is the contest inside the contest which is the one between bat and ball. A score of 200 now plays the way 160 used to. The currency has been debased. The number on the board went up and the value of each run came down.

That is the imbalance Sachin Tendulkar and Greg Chappell have spent the last few weeks describing in public. Tendulkar has put a set of fixes on the table. Chappell, in a column about the fifteen-year-old who just rewrote the record book for six-hitting, has called for the format to be rebuilt. And the data backs them. It’s not that the games are less competitive but something narrower and worse. The ball has stopped mattering.

Which leaves the real question. Why has the bat run so far ahead of the ball?

The wicket that costs nothing

Here is the cleanest way I can put it. The Impact Player rule is an insurance policy, and insurance changes behaviour.

This is a textbook moral hazard. When you protect a party from the cost of a bad outcome then that party takes on risk it would never accept if it were exposed. Give a batting side an extra specialist hitter and the top seven are no longer playing with scarce capital. There is always more batting behind. So the men at the top swing from the first ball, because the downside of getting out has been quietly socialized away.

The cost of a wicket has fallen to roughly zero. And a thing that costs nothing gets spent without thought.

That is the whole disease, and it shows up in the scoring. Powerplays detonate because there is no reason not to detonate. The middle overs, where a captain used to squeeze and a batter used to graft, have flattened into more of the same hitting. Nobody protects a wicket they are not afraid to lose. The totals climb, the sixes pile up, and a delivery that should have been an event becomes one more ball to swing at.

When Tendulkar and Chappell call for reform, they are not nostalgics. They are diagnosing the same thing from two ends. One of them is among the greatest batsmen the game has produced. The other is one of its sharpest cricketing minds. They are looking at the run glut and seeing what it costs.

Back the ball, not a rewrite of the game

The instinct behind all of these proposals is right. The wicket has to cost something again. The ball has to matter again. But not every one is worth backing, and the ones I would leave alone I leave for a single reason. You do not have to rewrite what cricket is to fix what cricket has become.

Two of Chappell’s three ideas are the cleanest in the whole debate. Live grass on the pitch and a harsher lbw. Grass gives the ball lateral movement, and a good delivery is dangerous again. The lbw change is simpler still. If the ball is going on to hit the stumps, give it out, and stop worrying about whether it pitched outside leg. That reprieve is a gift to the front pad. It pardons the exact delivery a bowler works hardest to bowl, the one that swings or spins back into the stumps from outside leg. Take it away and you have handed the bowler a weapon. Give him a few of those, more movement and more ways to take a wicket, and the balance starts to come back on its own.

The six-wicket cap is where I disagree and not because it is a bad idea. On paper it is the sharpest of the lot. Cap the innings at six and every wicket is scarce, and scarcity drags the caution back. The problem is the price of admission. Ten wickets in an innings is one of the few things every cricket watcher on earth already knows, the way they know an over is six balls. Change that and you are not reforming T20. You are inventing a new game and asking a billion people to learn it again. That is the mistake The Hundred made. It rewrote the grammar of the sport and hasn’t been able to find many takers. I would stick to giving options to bowlers rather than rewriting the basic grammar. So this one I would not back.

Sachin comes at it from the supply side, and here I am almost all the way with him. Kill the Impact Player and the insurance policy goes at the source. That alone does most of the work. Then let one bowler send down five overs. This is the idea I like best in the whole debate, for a reason that has nothing to do with any single match. It changes the market for bowlers.

Look at what the Impact Player era did to batting. It incentivized batsmen to take more risk, and risk-taking became a craft. Clearing the front leg and hitting straight is now a drill in every batter’s kit. Batting has been systematically upgraded. Nothing has done the same for bowling. The five-over allocation is where that starts. It builds a hierarchy of responsibility into an attack. Bowlers compete to be the one trusted with the extra over, the way the best batsman competes for the new ball. A bowler who can be handed a fifth of the innings is worth more at the auction than one who cannot, and that price signal is what pulls talent toward the skill. For Indian cricket it is a straight talent unlock. Hand a young quick a bigger job and we find out early who can carry it.

The split powerplay is the one Sachin idea I would leave. We have already run this experiment. ODIs brought in fielding and split powerplays years ago, and the tactics barely moved. Captains used the option on autopilot or sat on it because nobody was sure what it was for. And it fails the only test that counts here. It hands no power back to the bowler.

My two additions, and the one principle behind both

Sachin and Chappell go after the conditions and the bowling. I want to add a third front, and it is behavioural. The modern batter increasingly wins before the ball is bowled.

Both of my suggestions attack the same thing. Pre-meditation. The principle is simple. Make the batter react to the ball and not to a plan he formed at the top of the bowler’s run.

One free leg-side wide per over. Allow the fielding side one delivery down the leg side each over that is not called wide. The shuffle across the stumps has become a manufacturing process. The batter pre-moves to the off, exposes leg stump, and any ball that follows him is gifted as an extra. One free leg-side wide per over takes that manufactured advantage off the table. It is a cap and not a licence. Nobody can bowl an over of leg theory under it.

Batter stays in the crease till the ball is delivered. The batter must keep some part of the back foot behind the popping crease until the bowler releases. He cannot charge before delivery. The pre-meditated charge is the single most effective neutraliser of length in the game. Step out before release and a good-length ball becomes a half-volley and the bowler’s best weapon is gone before it lands. There is a fairness argument here too. The bowler is bound to a fixed line by the front-foot no-ball law. The batter roams free. Bind them both. And before anyone asks how you police it, we already call the bowler’s crease frame by frame with the third umpire. Point the same camera at the batter’s.

Neither rule asks the batter to be less aggressive. It asks him to react to the ball which is the version of aggression that was always supposed to be hard.

What we are actually protecting

Sports economists have a name for the thing that keeps people watching. The uncertainty of outcome. Demand for a contest tracks how unsure you are of the result. It is why leagues that want to survive build salary caps and drafts and balance into their rules. They are protecting the doubt of outcome because the doubt is the product.

By that measure the IPL still looks safe. The results are still in doubt, as the index shows, even though it’s declining. So why touch anything. Because the doubt has changed character. It used to be produced by a contest between a bowler and a batsman. Now it is produced by two batting orders swinging at each other until one of them finishes a few runs ahead. The final margin stays tight. The jeopardy on any given ball is gone. A delivery that can only be a four, a six or a dot is a slot machine, not a duel.

The IPL has spent two decades being the most inventive league in the sport, and that is exactly why it should be the one to act. Being ahead of the curve means knowing when an experiment has run its course. The Impact Player was a fair thing to try. It has driven batsmen to become fearless. Make them play for the team and not personal milestones.

Put the price back on. Give the ball the right to dictate terms again. We are not diminishing the next fifteen-year-old who breaks the single-season six record. We are making him earn it. Greatness only means something when there was a real chance of failure on the other side of the shot.

Sources and notes. The 20th Over Index, the run-rate, first-innings and six-rate series are my own work on Cricsheet ball-by-ball data, covering 1,241 IPL matches from 2008 through the 2026 season. No-results are excluded from the index and ties always count as close. The index definition is the strict one on the Methods and Sources page. The chase must reach the final over of its allotted overs, and the result must be a chasing win, a defeat by ten runs or fewer, or an all-out finish with a margin of ten or fewer. Greg Chappell’s argument on six-wicket innings, live grass and the lbw law is from his June 2026 ESPNcricinfo column on Vaibhav Sooryavanshi. Tendulkar’s three proposals, removing the Impact Player, a split powerplay and a five-over spell for one bowler, are as reported the same week.

In Dharamsala, after the fifth T20I against South Africa in December 2025, Suryakumar Yadav stood in front of a microphone he probably wished he could avoid and said the line that’s now followed him around for a year: “Not out of form, but definitely out of runs.”

You could hear the conviction draining out of it. He’d just been dismissed for 5. It was his 22nd T20I innings without a fifty. In that stretch he was averaging 12.84 at a strike rate under 118. Numbers that would get a debutant dropped, never mind a captain. ESPNcricinfo’s piece on what’s gone wrong laid it out clinically: 18 dismissals in 133 balls against pace, an average of 8.11, the weight transfer that used to be automatic now missing on the simplest drives.

He did recover. Against New Zealand in January 2026 he averaged 80 and got Player of the Series. He then captained India to the 2026 T20 World Cup. The trophy is in the cabinet. On the surface, questions about his place seem to have answered themselves.

They haven’t.

Surya is 35. The next T20 World Cup is in 2028. The LA Olympics where cricket returns to the Games for the first time since 1900 is also 2028. Surya will be 38 by then. Even the most generous reading of his trajectory says you cannot plan India’s next two-year cycle around him as captain. India doesn’t need to replace him tomorrow. But pretending the succession doesn’t need to start being thought about is the kind of thing mature cricketing nations don’t do. Australia didn’t wait for Ricky Ponting to fall off a cliff. England started backing Buttler well before they had to. We have time. We should use it.

So who’s next? The shortlist is short. Hardik Pandya is the obvious name but he’s also 32 with a back that’s spent more time in MRI scanners than on the field. Pant and Shubman aren’t automatic choices to XI. Which leaves two players who have actually done the job at the level just below international cricket, for long enough to leave a real evidence trail: Sanju Samson and Shreyas Iyer. Both command a place in India’s T20 set up.

This post is about what the data actually says about both of them as captains. Not vibes, not what a commentator said in 2022, not “he looks like a captain.” The numbers. I’ve pulled together every IPL match each has captained. 69 for Samson with Rajasthan Royals, 80 for Iyer across Delhi Capitals, Kolkata Knight Riders and Punjab Kings. Here’s what comes out.

The headline numbers

Samson has captained 69 IPL matches. Won 34, lost 34, one no-result. Exactly 50%.

Iyer has captained 80. Won 45, lost 31, four no-results. 59.2%.

That’s a nine-percentage-point gap. Across this many matches, it’s not noise. To put it in context: Dhoni’s career IPL captaincy win rate is around 59%; Rohit’s is similar. Iyer is operating at that tier. Samson is operating at the league-average tier.

And the gap is much wider when it matters most. Iyer has captained in 10 IPL knockout matches (Eliminators, Qualifiers, Finals). He’s been to three finals (DC 2020, KKR 2024, PBKS 2025), and he won one with KKR. Samson has captained in 5 knockout matches, reached one final (RR 2022, lost) and won zero titles. Even adjusting for the different opportunities, Iyer’s knockout win rate (50%) is better than Samson’s (40%) and the asymmetry in getting to the playoffs is itself a captaincy signal. Iyer’s teams have ended the league stage in the top four six times. Samson’s twice.

But the raw win rate alone is unfair to both of them. Maybe Iyer just got luckier with the toss. Maybe Samson played in a tougher era. Let me strip those out.

What happens when you control for the toss

The toss matters in T20 cricket. It matters more now than it has ever mattered. In IPL 2026, every single captain who won the toss has chosen to field, and chasing teams are winning 80% of their games; the highest chase rate in IPL history. The toss has gone from a coin flip to a near-decisive moment of the match, which means we have to think carefully about what a captain’s record looks like when you separate the two situations.

Samson won the toss in 53% of his captained matches. Iyer in 55%. Almost identical, so neither got luckier than the other on the coin itself.

But look at what they did with it:

• Samson, after winning the toss: 47.2% win rate. After losing it: 53.1%.
• Iyer, after winning the toss: 61.9% win rate. After losing it: 55.9%.

This is a much bigger deal than it looks at first glance. The toss has become the single most valuable decision in a modern T20. The captain who wins it essentially gets to choose to chase, which is the side of the match where you have an enormous information advantage and where the impact-player rule lets you load up your finishing power. Iyer is converting that advantage at 62%. Samson is converting it at 47%; worse than if he’d lost the toss.

This is genuinely strange. Samson is the rare captain who appears to underperform when handed the most valuable decision in the match. There are a few possible explanations. His bowling-first calls are wrong for the conditions or RR’s chasing setup hasn’t suited his decisions. But the pattern is clean enough to flag. Iyer is making the modern T20 toss work for him and Samson is not.

It’s worth giving Samson his due on the other side. In the impact-player era, the captain who loses the toss wins only 48.7% of his matches on average. Losing the toss is a real and measurable disadvantage today. However, Samson wins 53% when losing the toss, four points above that baseline. Iyer wins 56%, seven points above. Both are good at handling the disadvantage; Iyer is just better at it. The same pattern is true of most established IPL captains, with Rohit Sharma at 61% the gold standard and most others below the line. However, Rohit has had Malinga or Bumrah and Pollard or Hardik to close out games.

If you want a single fair-comparison number that strips the toss out entirely and averaging the two splits as if the toss were a perfect 50/50; here it is:

• Samson’s toss-neutralized win rate: 50.2%
• Iyer’s toss-neutralized win rate: 58.9%

The gap holds. It is not luck.

Their own batting got better, not worse

The default story about captaincy is that it weighs you down. You’re thinking about field placements when you should be thinking about the next ball. Most players see their batting numbers dip when they take the armband. Rohit Sharma was famously the rare exception.

Both Samson and Iyer are exceptions too.

Both bat better with the armband. Samson’s strike rate jumps nine points. Iyer’s goes up seven. Neither pays the captaincy tax.

Part of this is coincidence. Both took over captaincy roughly when they were also maturing as batters. Samson was 26 when RR handed him the job in 2021; Iyer was 24 when DC gave him the role in 2018. The 30s have been kinder to both than the early 20s. But the point stands: neither has the “captaincy is a distraction” problem that, say, a Rohit or a Steven Smith struggled with.

If anything, the data points to a slightly more interesting nuance. Samson is the more explosive bat in the death overs (strike rate 190 as captain), while Iyer’s powerplay strike rate jumps from 98 as non-captain to 127 as captain; a 30-point swing that suggests captaincy makes him more responsible up top, not less.

So far the case is: Iyer is the better captain by a clear margin, but both have grown into the role as batters. That’s the easy part of the analysis. Now it gets harder.

The harder questions

Win percentage is the outcome. It tells you who won, not how. To work out which of these two would actually do the captain’s job better at international level, you need to look under the bonnet.

Four things matter more than the win column.

The first is clutch. Anyone can win when their team is in front. A captain earns his money in the games where it’s tight. So I separated out every match decided by 10 runs or less, by 1 wicket, or in the last over. There were 28 of these in Samson’s career and 24 in Iyer’s.

In close games, Samson is 15-13. Iyer is 12-12. That’s the one major category where Samson actually beats Iyer. Samson is better in close games (54%) than in non-close games (48%). Iyer is the opposite, significantly better in non-close games (64%) than in close ones (50%).

What does that mean? It means Iyer is much better at building winning positions and then converting them. Samson is the one you want in the trenches when the match has gone to the last over and someone has to make a call about who bowls the 18th, 19th and 20th.

The second is fielding. I can’t measure where the captain sets the fielders and that data doesn’t exist publicly. But I can measure the consequences: how often the team forces dot balls in the death overs, how many catches they take, how many run-outs they create. These are downstream of where the captain puts his fielders.

Compared to the league average in their captained seasons:

• Iyer’s teams take +0.51 more catches per innings than the league. They force +2.6 percentage points more dot balls in the death overs.
• Samson’s teams take 0.29 fewer catches per innings than the league. They’re slightly below league average on dot balls.

Every fielding proxy points the same direction. Iyer’s teams squeeze in the field. Samson’s don’t. This is the one part of the data where there’s no ambiguity at all.

The third is how they back players. India’s T20 squad over the next two years will be made of seasoned IPL pros, not new caps. Hardik, Bumrah, Abhishek, Axar, Ishan, Arshdeep; names that have played 100+ IPL games each. The India captain’s job isn’t to develop them. It’s to back them through bad patches without panicking or utilize bench strength for the right match ups.

So I asked: when a senior player had a bad day under each captain and batted 10+ balls and scored under 15, or bowled two overs for 20+. Did the captain pick them again the next match?

• After a batting failure, Iyer keeps the player in the XI 41.7% of the time. Samson 31.8%.
• After a bowling failure, Samson keeps the bowler 35.9% of the time. Iyer 32.0%.

Iyer is meaningfully more patient with batters. Samson is slightly more patient with bowlers. Both numbers are modest because IPL teams churn aggressively, but the directions are real. For an India dressing room with locked-in match-winners with the bat, Iyer’s pattern is probably the more useful one.

There’s a counter-pattern worth flagging for Samson though. If you look at core stability on how often the same top 11 players (by total appearances that season) all play together then Samson keeps his core 11 intact in 22% of matches, Iyer only 14%. Samson uses more total players across a season (20.2 vs 18.8) but holds a tighter nucleus together than Iyer does. The two patterns aren’t contradictory; they describe different captaincy styles. Samson tends to rotate fringe players around a settled core. Iyer is more willing to disrupt the core itself in pursuit of matchups. Both are defensible. Which one fits India’s situation better depends on whether you think the senior players need protection from bench pressure (Samson’s pattern) or whether you think the squad’s depth means matchup-driven changes have to override loyalty (Iyer’s pattern).

The fourth is how their teams actually play, beyond the win column. This is the most damning data for Samson and the cleanest for Iyer.

If you measure each team’s run rate by phase (powerplay, middle overs, death) against the league average in that same season, you get a clean picture of whether the team is actually playing better cricket than its competition.

Iyer’s teams beat the league average with the bat in all three phases. They’re better than league in the powerplay (+0.23 runs per over), in the middle (+0.28), and in the death (+0.06). With the ball, they concede less than the league in all three phases including a remarkable −0.48 in the death overs, which is the hardest phase to bowl in.

Samson’s teams are essentially league-average overall. They beat the league with the bat in the powerplay (+0.16), but bleed runs in the middle overs with the ball (+0.40 worse than league average) and are neutral elsewhere. There’s no phase where Samson’s teams are visibly better than the competition.

Tactically, this also shows up in matchups. Samson uses spinners for nearly half his middle overs and a quarter of his death overs which is much more than Iyer (35% middle, 10% death). But Iyer’s spinners deliver better results than Samson’s in every spin matchup. Spin to right-handers in the middle: Iyer’s bowlers concede 7.4 runs an over; Samson’s concede 8.2. Pace to right-handers in the middle: Iyer 8.5; Samson 9.4. These aren’t huge gaps but they’re consistent across every cell of the matchup table. Samson is deploying spin more aggressively and getting less out of it.

The case for each

The case for Iyer is the obvious and accurate one: he’s just clearly the better captain on the evidence. He wins more. He wins across three different franchises, which means it’s not a one-team fluke. He has been to three IPL finals and won one. His teams beat the league average in every phase of the game. His bowlers get more out of every matchup than Samson’s do. He backs his batters longer. His fielders take more catches. If you were doing a blind comparison and didn’t know either name, this isn’t a close call.

The case for Samson is harder but real. He’s the better clutch captain and the one you want when the game has gone to the wire and the call is whether to bowl Bumrah in the 18th or save him. He’s a wicketkeeper, which means his captaincy decisions are made from behind the stumps where he’s got the best view of the field, batsman and situation. And he’s done his work at a single franchise where he didn’t have a strong supporting captaincy infrastructure. Iyer benefited from coach Ricky Ponting at DC and Gautam Gambhir as mentor at KKR; Samson at RR has had less of that.

There’s also the role question. Iyer is a middle-order anchor. India’s middle order is, depending on the day, three or four deep already. Iyer comes in if he replaces SKY. Samson is a top-three batter and a keeper. Samson is already a part of the team. If you have to lose someone from the XI to fit your captain in then you’d rather lose a middle-order spot than a keeper-opener.

What we’re actually choosing

This isn’t a debate about who’s the better captain. The data is clear on that. It’s a debate about which captaincy style India wants for the next two years, and which player fits the XI you can field.

If you want the safer, higher-floor captain and the one whose teams just play better cricket overall, whose fielders take catches, who has been to finals and won them then it’s Iyer. If you want the higher-ceiling clutch captain who happens to also be a keeper-opener that solves a real team-balance problem, it’s Samson.

Personally? I think on pure captaincy quality the answer is Iyer and it isn’t particularly close. But I also think the keeper-opener role and the team-balance issue is a serious enough factor that Samson is the more pragmatic pick for Team India.

The wrong answer is to do neither. The wrong answer is to wait until Surya is 37 to find ourselves with no T20 captaincy bench and panic-promote whoever happens to be in form that month. We have 2026, 2027, and most of 2028 to build a captain. Both of these players have already done the apprenticeship. The next series is the time to start.

We are a mature cricketing nation. Let’s act like one.
