as a boxing fan I would say that Mike Tyson in his prime would KNOCKOUT Ali.... BUT... if he did not knock him out the Ali would win because of his stamina and his heart. Tyson hits MUCH HARDER but Ali's brain works MUCH BETTER, in his prime of course
OFF TOPIC a little but point proven...
Just like if you took Jordan in his prime vs. Lebron RIGHT NOW in a 1 on 1 game Lebron would DOMINATE simply because of his size. The new breed of athlete is much bigger and stronger than athletes in the past. You can try to argue that but it is fact. I could not think of 1 player during the Jordan era who was built like Lebron, closest thing is Shaq when he came to the league and he was 7 foot 2 or 3 and Lebron is 6 foot 8.. BEAST
