Who does better assume the rounds are 12 to make it fair for Mike Tyson. I still believe Frazier does better, because he had better conditioning by a lot.
I think Ali has him beat before he steps into the ring. Those constant Ali insults and his belittling of opponents & Tyson would be the guy getting ridiculed for 6 or 8 weeks.
Joe for his constant pressure and the way he worked at close range. Mike was dangerous when he had had the space tothrow his big shots, but let himself get held to easily when his opponent wrapped him up. That's before and after he went to prison.
