As much as I am a fan of Warney, 'The Don' is in a league of his own. His record has stood the test of time. No batsman has come close to emulating his sensational Test batting average of 99.94.
Warney, the best bowler of all time. Bradman the greatest cricketer of all time.
Would his average have been so good had he played as many tests as they play today? would his average been so good had he played against the quality and speed of the bowlers of today?
Both very arguable, I would put money on his average decreasing to around the 50's, just like the greats of today.
I am in no way saying that Sir Donald Bradman is not a great cricketer, I am just saying you can not compare current sports starts to sports stars from years back.
