Yes, I can name plenty of Batsmen who I would rate over Bradman because I never saw him play nor did see the standard of cricket that was being played.
True, however You gotta take into account eras.
In bradman's era cricket wasn't a money making machine, hence most players including bradman had other jobs. Bradman was stockbroker first and cricketer 2nd. Meanwhile cricketers in this day and age has recieved life long coaching and training since the age of 8-13.
Secondly bradman's era didn't have chest platings, helmets or even proper functioning bats making cut shots, sweep shots and unorthodox strokes impossible. Pitch ciration wasn't as good either.
Every one with the same resources as Bradman avg 40 to 60 but Bradman avg 99.94.
Take someone like Pointing back to 1930's and remove his skills, training, coaching, money and have him only play cricket part time while working multiple jobs + Those old bats and what not, then he'd probs be another 40-60 avg batsmen.
Logically I don't think bradman is better then even players like Labu. However again Labu is born 100 years after bradman.
Take labu back to 1930's with the same resources and he'll be avg 30-50 and would be way way way behind bradman as a player.
That's why it's useless to compare such long eras.
It's like saying Magnus is > Bobby fisher in chess, it's true however Magnus had access to practising with stockfish and supercomputer Ai engines. Magnus would get smoked in chess had he been born in Bobby fisher era
