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.

	Avg as captain	Avg as non-captain	SR as captain	SR as non-captain
Samson	35.9	31.1	146.1	137.5
Iyer	35.8	34.2	138.7	131.3

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.
