When the Indian Premier League began a decade ago, my fellow cricket purists bemoaned what they called a tamasha version of the game. I was an enthusiast, though. I was baffled that so many people felt a three-hour game was too short to be taken seriously as a sport. Football lasts 90 minutes. Hockey is an hour. Tennis, badminton, basketball matches all tend to be shorter. None of them lack nuance or complexity or drama, and are rich in strategic and tactical options. So why should T20 cricket be any less than that?
I expected T20 cricket to have a number of positive effects, and it has delivered on all those counts. It has widened the pool of players who can make a healthy living by being professional players. It was broadened the audience for the game, as many more people are willing to spend three hours watching the game than than they would be to spend five days. And it has enriched the other forms of the game.
Cricketers are now fitter than ever before, and batsmen and bowlers alike have developed tools in their arsenal that were not necessary before. The shorter format demands greater urgency, and players have to approach the game differently. Intent leads to ability. A batsman who needs to play an aggressive stroke to every ball will develop a better repertoire of aggressive strokes. A fielder who is desperate to save every run he can will be fitter, and will have better technique. Bowlers, in turn, will have to adapt to more aggressive batsmen by pushing the limits of what they can do. (And indeed, contrary to early stereotypes, T20 cricket isn’t a bang-bang slog-fest, and bowlers remain matchwinners.)
This has percolated down to Test cricket. Nostalgia makes us overestimate the past, but in terms of pure skill, modern greats are a league above the legends of the past. This is not because they are inherently more talented or hard working. It is because, as an economist would say, the incentives are different. T20 cricket demands more from them, and they have adapted.
I consider T20 cricket to be a separate sport, all on its own, and in that light, the last ten years have been fascinating. We have seen a new sport evolve out of the framework of an old one, and every year has seen the game develop rapidly. The key strategic development has been in the structure of the game itself.
Teams initially came to T20 with an approach transplanted from one-day cricket. Every innings had three broad phases: pinch-hit, consolidate, slog. But this was a mistake. In ODIs, teams have around seven batting resources for 50 overs. In T20s, they have the same number of batting resources for 40% of the overs. The reduced overs mean that the opportunity cost of a dot ball goes up, and the opportunity cost of a wicket goes down. The risk-reward ratio changes, so batsmen should attack more.
In fact, they should frontload, as I like to say – they should begin with attack, and attack all the way through. A team that bats through 20 overs losing only three wickets has probably wasted resources, given the batsmen waiting in the pavilion. They should have attacked more; every over can be a slog over.
Some teams understood this, like West Indies in the last T20 World Cup, or Sunrisers Hyderabad last year. But many teams still don’t get it. I wrote before last year’s IPL that teams are underestimating par scores and not frontloading, so anyone into cricket betting should blindly bet on the team batting second, as the team batting first will score less than optimally. That’s exactly what happened. Out of the first 14 games, 13 were won by the side chasing in an average of 17.2 overs, with an average 6.6 wickets in hand. (Teams adjusted in the second half, so follow that advice this year only for teams that don’t frontload.)
The most important statistic for a batsman, thus, is his strike rate. We might consider a strike rate of 125 healthy by ODI standards, but it is pathetic for T20s. A team batting at that strike rate would make 150 runs, which is well below par. A batsman playing at that strike rate is, thus, a liability to his team – the more balls he faces, the more he is letting them down. (As there should be no consolidation or innings-building phase in T20s, there is no ameliorating factor over a season.)
So here’s one stat you should keep your eye on this season: a batsman’s season-long strike rate minus the overall par-score strike rate (for a par score of 180, that would be 150). Let’s call it the Varma Number. If it is negative, the batsman has failed.
