I've consistently said that's his biggest weakness and a possibly probative to him being in the ultimate top tier. And yes, it matters.
But not sure if that falls under better, but point taken and taken under consideration.
The max 4 to 5 over spells are just as damning as missing matches.
As the opposition, he scares me more. Against great batsmen, he still scared me more.
Let me put it this way, against Warne, England lose this game easily. We lost 378/3 game in 2022 too.
Why? because Warne couldn't be just blocked out, he'd be a constant threat, Bumrah is not, Warne would play all 5 games, Bumrah is at a point where he can only play 60% of the games in major serieses, let alone nothing games.
Let me make an analogy, take them as pro wrestles, Bumrah moves faster, sells better and does everything better but Gasses out in 10 minutes, Warne keeps up with Bumrah in quality and has much greater endurance and can keep up for 20-25 minutes, it's obvious who would have a better body of work due to their endurance, and therefore Warne would be regarded as better.
Take Dynamite Kid/Tom Billington as Bumrah, and Rey Mysterio Jr as Warne, nobody would disagree that the prior was pound for pound the most skilled performer, but the body of work matters and how you get to that body of work also matters, and therefore the latter is better. Same for Warne vs Bumrah.
if this was Bumrah vs Underwood, then sure, the gap in quality is too much, but these guys are similar enough in quality that it's not the same thing at all.
