Tim Tebow! :D Seriously though, if I had to pick the most dominant athlete from the 3 most popular sports, I would pick.. Shaq in his prime. MJ too. What about Barry Sanders? I am asking out of pure curiosity because I was too young to know what I was watching when I watched him play. Exactly how good was he??
Barry was flat out the 3rd best running back of all time, according to his father Barry was the best back I have ever seen.
Where's the MMA Love, kind of difficult considering weight classes, and those who are the greatest eventually get old and lose several times before they get the picture... But right now... Anderson Silva is the best pound for pound, the greatest of his sport, GSP would be close, but Silva does it in dominating fashion...
