George Foreman

Rocky Marciano

Muhammad Ali

Larry Holmes

Answer 1

he could knock out anyone he wanted to in his prime. in his prime, he knocked out the no.1 contender in :18 and the no.2 contender in :14, and nobody else could punch like that.

Answer 2

dempsey could take on them all in his prime he was a animal one of the very few white fighters who had tough skin he hit like a mule and had descent speed i think ali would beat him but dempsey would go 15 rds he would have given frazier trouble as well as marciano liston or foreman would probably have knocked him out but not without a brawl joe louis would of had trouble with him i think that fight would of went 15 rds with louis winning on points possibly scoring a knockdown by either fighter mike tyson would of kod him after a long brawl holmes and lewis probably would have gone 15 rds with him unless dempsey nailed lewis in the chin holmes could take a punch better than lewis he could take them all on
