I think that the greatest sportsman ever is Sir Donald(the Don) Bradman.

He is so far in front of any modern or past player. His batting average of 99.94 runs per wicket is roughly 40 runs ahead of any other player past or present.

List me one player of any sport who is 66% better than the next person in their chosen field. I don't think you will find many.
