Heres my opinions based on here and there historical research on Sir Donald George GOAT Bradman , and cricket of the times
The ovals in Australia in Don Bradmans playing days were bigger, hence by definition it would have been harder to score boundaries
Don Bradman scored quickly ,looks like he scored close to a run per minute in a lot of innings, teams invariably dont do that these days
The pitches were uncovered in his days, so he would have batted on some difficult sticky wickets in some innings
The question I will raise is, if the bowlers were no good in his playing days, why did he have a batting average close to double most other good batsmen of the times?
A comparison of sorts these days would be
Steve Smith averaging about 110 with the bat
Gary GOAT Lyon averaging about 10 per test wicket
Or for more of a view on how much better Bradman was in his day it would be akin to Ken farmer kicking about 200 goals in almost every season he played in the SANFL
I have only posted , with some considereable bias toward Don Bradman
We dont know if he would have been as good now, with the amount of Test cricket played , the bats, etc etc
But the undeniable fact is, anyone who averages close to twice as much as the best of the times, in any sport,in any era , is freakish
