Don’t want to ruffle any feathers but Marciano was not the puncher that he is given credit for. KO ratios only tell one side of the story. I think he would have been a Chuvalo in the 60’s and 70’s. Marciano is an American folk hero and was a tough sob in his time but lets be honest here. He fought in arguably the weakest era in heavyweight history. Charles was far from Charles, who knows how old Walcott was and Moore was a shadow of his former self. To the punching power, their have been plenty of bigger punchers then Marciano since his day and before him. You want to talk about a small heavyweight with a punch then how about Langford? What about Satterfield? You don’t see his name mentioned on to many top 5 punchers lists. Max Baer could punch. Shavers goes w/o saying. It’s great what Marciano did but people really need to put things into perspective. I suppose the biggest unknown in these hypothetical comparisons is the “times”. Even if one had a time machine to put these match-ups to the test, you could not beam over “way of life” Nod goes to Marciano on that one although he’d be just as fk’d up being beamed to 1972 let alone 1990 as anyone else being beamed back to 1952.
