The rate of evolution of T20 cricket is the root cause of my gripe about the way that the commentators are approaching the game and informing the audience. This particular form of the game is moving very quickly I think - driven by monetary rewards (and willingness to throw money at the form to chase those rewards).
Without getting into the numbers, my gut feel is that you are right. A few years ago, it felt like par was 160 and now it’s more like 180, with teams more regularly breaking 195-200. We’re starting to get analysts looking at performances and saying things like “Player X cost his team the game, he only scored at a SR of 130”, which would have been unthinkable not that long ago.
And Root, and in particular his role in limited overs cricket, is an interesting case study in how readily the game has changed. Back in 2016, he was very important in England’s run to the World Cup final. Now he can’t get in the team. The question of whether you have an anchor in your team anymore is indicative of the rapidity with which the game has changed. It seems now, at least give the way selection is going, you maybe don’t want one!
Bearing in mind that England have Buttler, Stokes and Roy all not in the current line up - I think that they’ll try and go all guns blazing and not have Root in the side (keeping Banton and Bairstow in the team - albeit with one or both moving down the order), on the basis that Buttler or Morgan could adapt and do the anchor role on the fly if England fall to 20-3 in a game, but otherwise, you don’t want someone who doesn’t score at nearly 200 SR - or is at least capable of flicking the switch and putting in a period of 12 balls where he scores that quickly.
It’s different in 50 over cricket where there is more time and a well played innings at 120 SR for 80-100 could well win you a match. There’s just so few deliveries in a T20 game that even the approach that Chris Gayle takes (get your eye in, block a few, and then back yourself to catch up by going tonto) is being looked at as a bit of a relic. Now it seems the philosophy is you go hard, all the time.
And all of this has unfolded in 4 years (bearing in mind Root’s importance in 2016). T20 is a crazy game from an evolution perspective.
Up thread, there is a comment about how light the batting looked for England. That’s another one which is really strange. I’ve seen some really unbalanced teams go out in various T20 comps - 5 recognised bats (including a wicketkeeper) and 6 bowlers, two or three of which can swing from the hip but not much else. Looking at the numbers, your #7, if he bats at all, will only face on average 6 balls (guys below that even fewer). Teams seem to be saying that you don’t want a real allrounder down there - you just want someone who lashes it and if it comes off, great, since you’re probably already in trouble if your 7 is batting. Instead, they seem to prefer to carry more bowlers to defend totals, since if one of your guys has an off day but you’ve only got 5 guys who can bowl, he’ll have to bowl his 4 overs and could lose you the game as a result.
So side composition is also evolving rapidly, and teams are willing to try out new tactics to see what works - back their upper order batsmen to come off and then hope they have enough bowling options to cover all eventualities. Indeed, in IPL, the sides who go big in the auction on batting (particularly RCB) have been found out for thinking it’s a batsmen’s game. The teams that do well have tended to spend on better quality bowlers, which is really weird, given the prevailing view of T20 is one of balls being smashed out of the park, but it also makes a certain degree of sense when you think about it.
Finally, in this stream of consciousness post, you’re even getting people suggesting things that haven’t been seen yet. For example - say you’re an IPL franchise and you’ve somehow picked up Stokes and Jason Holder. They’re in your 5 best batsmen but both can bowl too. Is it worth picking the very best wicketkeeper you can find regardless of batting talent and just batting him at 11? It might save you more runs and take you more wickets than picking up a worse wicketkeeper and better batsman, especially since you’ll have 6 or 7 potential bowlers in your line up. I don’t know the answer, and it hasn’t really been tried yet, since you need the right side composition to make it work but who is to say?
I much prefer Test cricket to T20 but I find it difficult to deny that T20 is currently in a really interesting place with how the game is going. Eventually, a “winning” set of strategies is going to be found and the sides will become more homogenous in structure and in the cricketers in those structures, but right now it’s a really exciting place for the game to be in, as we’re seeing it transition before our eyes.
