Paper covers rock, scissors cuts paper, rock breaks scissors.
Frasier beats Ali, Foreman beats Frasier, Ali beats Foreman.
Jack Johnson fought Langford before becomming champion and won, but it was the hardest victory of his career and he flatly refused to ever meet Langford again. Foreman punched as hard as Tyson and I believe that Foreman was a smarter fighter. Could Ali have rope-a-doped Tyson? I believe yes, but we will never know. I also believe that Larry Holmes could have used his awesome jab to hold Tyson at bay until he ran out of steam. Could Sugar Ray Robinson beat Sugar Ray Leonard in their respective prime? Marciano was tops in his day but how would he do in another era? How would he have done against a much bigger Lennox Lewis? Was George Chuvalo the toughest heavyweight ever (fought the best and never off his feet)?
It is subjective questions like this that still fire my interest in boxing, not what it has become today!
