On the other part of the debate - Bradman. I do think people underrate how good Bradman was because we haven't seen anything like it. Bradman averaged 50% more runs than Steve Smith. Smith has been mind blowing. Bradman was way better than him. We can't truly comprehend how good he was because we don't really believe it. We don't believe it because we have no Anchor for our brains to work with. Bradman was as much better than Kane Williamson as Kane Williamson is to Pat Cummins.
Let's just look, for example, at the 1936/37 series, which by Bradman's standards was an average one.
In that series he made:
38, 0, 0, 82, 13, 270, 26, 212 and 169.
That was an average series for him. He "only" averaged 90 that series. That's akin to your average series being Michael Clarke 2012 level. It's unbelievable.
Basically, to say that Bradman would have averaged 60 today, you need to be saying that the best of the rest would be averaging around 30 today. Do we really believe that Hobbs would have averaged less than Travis Head?
Bradman might have "only" averaged 80 vs the 80s attack, but he's also wearing out the opposing quick bowlers, ensuring the middle order faces a softer ball and piling up massive totals. He was ridiculous and is banned from drafts because any side with him in is basically going to win unless there's a heavy, one sided advantage given to the opposing sides.
A bowling example would be like if every bowler was at Srinath level and one bowler was Marshall.
