Well I can't prove anything. But yeah, I'd back him to average
the same. If not more. You're right that bowling has advanced a lot more since his time
period, and the variety now would not have existed back then. But, batting's been made
easier as well. There's helmets, flatter pitches, shorter boundaries etc.
Plus, even the bowling standards of the '70-'90's does not hold a stick to the tactic of
bodyline. You either got hit, or got out. And yet, Bradman still managed to average more
than 50.
Obviously, again, I can't prove his fitness. But with someone with superhuman
determination and concentration, I would back him to rise to the fitness demands of today.
And you're still missing the fundamental point. The one thing that has been consistent
across ALL generations of Test cricket is that all the great batsmen have averaged in the
range of 40-60. Apart from Sir Don - who averages twice as much as any other GREAT of the
game.
His superhuman ability to concentrate for long periods of time was his greatest attribute.
And that's what sets him apart.
I guess Bradman faced bodyline in just 1 series, people like Gavaskar faced the brutal WI bodyline bowling with ease in so many matches. And I think helmets just makes it easier to face fast bowling(mostly bouncers), but playing reverse swing, and quality spinners like Murali, Warne, Vettori, Saqlain, etc. need a lot of skill, helmets have nothing to do with it.
And secondly there are many strategies used to avoid batsman from scoring or trying to target a batsman's weakness, the batsmen have to concentrate a lot and overcome all these things, these things didn't happen before apart from the Bodyline series, there was no science of fielding in Bradman's time.
And you cannot say that pitches are flatter in current era, the pitches were most suitable to batsmen when Bradman played, there were mostly batting pitches, only difficulty was sticky wickets.
Before 1920, the wickets were bowler friendly,
between 1920 to 1960 the pitches were batsmen friendly,
Since 1970s, there has been a balance.
And this is the reason why most of the batsmen with the highest averages belong to the period from 1920 to 1960.

I know that Bradman has achieved an average of 99.94 which is much higher than the averages of all batsmen across all eras which has ranged from 40 to 60, but he played against 1 good team and 3 minnows,thats where the main difference is created, the number of good teams Bradman faced were 1(in 2 countries) and current batsmen face atleast 7 good teams in different conditions and different kinds of grounds which makes adaptability a very huge factor, not to forget adapting to the shorter formats aswell along with the busy schedule which demands high level of fitness.
Bradman might have had superhuman determination and concentration, but players like Dravid, Kallis, etc. have had the same qualities, yet they are not able to achieve an average which is above 60 or 70 because of the quality of bowling and fielding they have to face.
Its true that Bradman has dominated his era like no other, but the problem I have is that other great batsmen, from the other eras have achieved perfection, have faced the difficulties which didn't even exist in Bradman's time, yet they are rated half as good as Bradman, that's not fair at all, Bradman was the best of his era, but comparing him with someone else who played in a completely different era where the game has changed a lot is not right.
