I am not a boxing aficionado but I will never understand how Tyson is not in the running. He had most opponents beat before the bout and his sheer knockout force was simply unmatchable.
I have a neighbor Burch who is 70 and a good friend and he knows boxing and insists Casuius Clay is the best ever. I say Tyson would have knocked him out. We will never know.
Tyson just demolishing dudes.
