I will argue this to the end, but Marciano was more like Cotto than like Tyson in terms of his punch. He would break guys down round after round, and then he would be able to KO them. Also to Nick it wasn't that he didn't fight everyone that was available as much as there was nobody available when he fought... Ezzard Charles was really old, and a naturally smaller guy in the first place, Joe Louis was comming out of retirement and he was really old. Walcott was already very old as well, and I might add that he was really outboxing Marciano, but he just was too old. IMO Marciano was in one of the weakest divisions the heavyweight has seen probably third after the heavyweight division a couple of years ago, and the holmes reign division.
