A statistician by the name of Charles Davis did an analytic study of the stats from a group of prominent global sportsmen a while back, and concluded that "no other athlete dominates an international sport to the extent that Bradman does cricket". To show how dominant Bradman was, Davis said that in order to be considered on an equal footing with Bradman's achievements, the greatest baseballer would need a .392 career hitting average, a basketballer would need to average 43.0 points per game and a golfer would need to win 25 majors (the records, by the way, are Ty Cobb with .366, Michael Jordan with 30.12 ppg and Jack Nicklaus with 18). Read as much, or as little, into that as you like. Either way, what he did was phenomenal (and FWIW, I would have loved to have seen Jack Hobbs play - he's a hero of mine).
