Joe Louis Muhammad Ali George Foreman Evander Holyfield Larry Holmes Jack Dempsey Lennox Lewis Sonny Liston Mike Tyson Rocky Marciano
Liston was way too green in 1955 to beat Marciano imo. Liston was not waiting for ten years for a title shot(Like myth would have). He became a contender in 58. And got his shot in in 62. 4 years. Other contenders waited longer than Liston did for a title shot(Archie Moore, and others come to mind,) And others like Wills or Langford could sit at number 1 forever and never get a sniff at a fight with the champion in the ring.
