Brockton don't be silly i know your Rocky Marciano fan, but unbeatable ? no far from it. And many guys pounded Muhammad Ali's body and it did nothing at all. Rocky Marciano never beat one great Heavyweight in there prime where as Muhammad Ali did and proved himself, Rocky Marciano never looked unbeatable he was knocked down/cut/hurt by former Light Heavyweights.

Guys like Holmes, Ali, would bust up Rocky Marciano so bad. Can you imagine a prime Larry Holmes 6'3 215 pounds, ramming that piston like left jab on 5'10 Rocky Marciano ?
