Scoring rate is one of the things I think people get wrong about Bazball. The idea is not so much that scoring means you score more runs but that because you score more runs, more quickly you end up with more time to take 20 wickets, to chase down a score or to come up with different ideas or to take advantage of changes in the weather or whatever. It's a classic sports analytics play where learning how and being willinging to take increased risk makes it more likely you will win more often, not that you will necessarily win this particular game. It's going to be fascinating to see how it works in the long run when more statistics are available and if it turns out that playing this way actually increases a team's likelihood of winning games.
The counter-argument of course is that it's really a function of Bazball at all and has only be working for England in the last year because they happen to have so many batsmen who can score very quickly and creatively and a couple of middle-aged outlier bowlers who can magic up some wickets from nowhere. It might well all fall apart once they no longer have this particular group of players.
It's also interesting to me having followed very similar debates in American Football where all sorts of "accepted wisdom" type rules of how to play and win are getting thrown out as people start to look at how these very analysable / statistic laden games and what everyone thought was true actually wasn't and my sticking to the old rules coaches and teams are often leaving value on the table.
Just spitballing here, so don't all freak out. Analytics really is fascinating and if it's going to change any of the English sports, surely it will be cricket.
