This adjustment will take Bumrah's bowling avg to 14 and Rashid Khan's to 10.
I don't think it's been uniform anyway. I think this era's stats inflation has disproportionately benefited the better batsmen.
The reason being that the hardest part of batting is playing yourself in. Scoring your first 20 runs is harder than any 20 after that. Making that period easier disproportionately helps the guys who are better batsmen because once they are in there far more likely to go large than batsmen who aren't as good (think unforced errors in tennis).
So what we have is that the best 3 batsmen of the best 6 teams have way over inflated averages while the ordinary batsmen might improve by 10% and the bowlers by nothing at all. And the better you are the more it inflates your average.
It won't hurt the best bowlers too much since they won't exclusively be bowling to the best batsmen. So Bumrah in another era might adjust down to 18 during this purple patch and Rashid down to 12 (or maybe not at all, the bloke averages 14 ffs).
Everyone knows Kohli appetite for huge scores once he's in (in both tests and ODIs), so it makes sense that if he's able to play himself in more often he can better take advantage of that.
And maybe that was true of Bradman.
I'm not trying to diminish Kohli here, I'm lamenting that the batting stats of the last few years cannot be trusted at all, given batting is so much easier than it used to be.
In 2000 there was one ODI batsman averaging over 60 (min 300 runs) and 5 averaging over 50.
In 2003 there were 3 and 8
2006 - 0 and 3
2009 - 2 and 11
2012 - 7 and 8.
2015 - 4 and 19
2018 - 10 and 18
Going from 0-2 batsmen averaging >60 in the 00s to 4-7 batsmen in the 10s is massive. Going from 3-11 batsmen averaging 50+ in the 00s to 8-18 in the 10s is equally ridiculous.
The 00s wasn't even bad for batting either, it was considered the best decade for batting in ODIs until that point. The fact that the ease of batting has dramatically increased since then is just crazy.
