May sound like a silly question, one is dead and the other far into Parkinson's tragically, but back when both were alive and in their prime, who would win? I would say in the boxing ring, and with boxing style rules, Ali would win. He was incredibly quick and agile for a big man, almost a foot taller, close to 100 pounds heavier, and he would be in his element. In a no holds barred street fight, I think Lee would win with an incredibly quick kick to Ali's knee. Certainly it would be a fascinating contest, to see who would win, would have been a good scene in "Game of Death" to be sure...
