When you look at Kareem's body of work, it becomes hard to rate anyone above him. Quite possibly the best high school and college player in history, more NBA MVPs than anyone else, 5 rings, ridiculous.

But the guys above him were better at maintaining that focus year in and year out. see more on Wilt Chamberlain
