"Yeah I meant Archie Moore... Jersey Joe Walcott was an old man by the time he fought Marciano though, past his prime."
He had just won the World Heavyweight Title(pre-alphabet days, he was the Man) from Ezzard Charles by knockout and fought one of the best fights of his career against Marciano despite coming out on the losing end. Walcott didn't peak until he was almost 34, he was one of his history's craftiest fighters and a freakish athlete that kept his quick hands and feet until the end of his career. Archie Moore was a LHW but he won the right to face Marciano by beating the number one heavyweight in the World in Valdes, only elite heavies like Patterson, Marciano, and Ali would beat Moore once he hit his stride; great company if you ask me. Charles was an All Time Great LHW and a very good Heavyweight Champion. Marciano also has very good wins over contenders like Layne, LaStarza, Cockell, and Matthews.
