I was about to compose a long rant/analogy comparing the skill difference implied by Bradman's career outcome to be something that might be expected by the god emperor of mankind in Warhammer 40k, not an actual human, and analogizing the different levels of cricket to the tiers of superhuman found in that universe.
But instead I'll ask this:
Bradman achieved 100 average from 52 Tests spanning about 14 years (taking away the war years). Also averaged <95 (can't be bothered calling exactly) from an addition 182 FC matches in Australian FC level.
Do we know of any player playing cricket at any level, achieving a comparable statistical batting feat? Surely there could be a ringer somewhere playing multiple levels down who equalled this over a similar span/match number? I'll take any half decent source as evidence, btw. I think it's unlikely it would even be tolerated.
And "tolerate" is the correct question to ask about such a level of dominance. We like to consider the world, environment, media, fans etc. as something like impartial observers when analyzing statistical achievement. But just as we cannot observe an electron without influencing it's velocity and momentum via a photon, our observations of the all time greats of any sport are not impartial, and I think there are significant cultural and historical factors that explain the reaction and tolerance of the greatness of Bradman.
We all know about the "tall poppy syndrome", and how the norm is to cut down the tall poppy. In the modern (~20th century onward in this context) history of sports in the Western world, the general rule is that the greatest performers are most often cut down in this way, with rules set up to curtail the extent of their dominance, i.e. Wilt Chamberlain in basketball with free throw rules, and legislation of physical contact.
All things equal we would expect the same tall-poppying of the extraordinary performance of Bradman. But all things are not equal (putting aside race in this case, which is another factor all-together to consider). The era in which Bradman played WAS special, in that out of the relative prosperity of the last century and a half, it was the time of the Great Depression, WWII break, and the immediate postwar years.
This reminds me of the old episode of the hit children's cartoon
Recess , in which they uncover a book of rules of the old King Mortimer.
https://recess.fandom.com/wiki/King_Mortimer . The children of the playground are dumbstruck from how silly the rules seem in their prosperous context. And so too I believe there was something different about the psyche of the observers of cricket during the Great Depression, a setting unlike any of the others of the relative prosperity of the last ~125-150 years in the Western industrialized sporting context.
In that context the tall poppy effect may have been flipped. The struggling common man could be inspired in a superheroic way by the otherwordly achievement of Bradman in a way the cricketing establishment might unconsciously have felt they needed to facilitate. In fact, the stark reaction to the singular mid career moment in which he actually received the sort of boundary testing resistance that would be welcomed in most sports, is telling. Instead of celebrating the Bodyline tactics that Jardine executed via the bowling Larwood and Voce, instead there was a great public and official outcry at the happenings of the tour. Rules were changed to prevent such a thing ever being used against Bradman again, but although short pitched bowling in and of itself was not outlawed, and only a framework built around it, the short term effect for Bradman's career was I believe sealed. No one was going to risk facing the kind of derision and career impact that Larwood's villification, for instance, brought him. Which is ironic, as improvements in pace bowling, and the use of short pitched ball as part of a pace battery would mark the transition into modern cricket brought about by the West Indies of later decades.
The career of Bradman was one of absolute excellence at a craft during it's golden era. Greats in other sports and games also find outsized success in early era's of a sports development, be it Babe Ruth in baseball, Wilt Chamberlain in basketball, Pele in football, Paul Morphy in chess, etc. etc. But the lie of the statistics detailing Bradman's excellence is that it would necessitate us putting him ahead of the greats in any other sport, or even the more modern greats of our own sport of cricket, due to their sheer magnitude. Bradman was a unique product of a combination of unique historical moment, cultural and sporting environment, and no shortage of skill, amalgamating together to produce something insane. Extrapolating any further beyond that is a mistake we would do well to avoid.
