Speak! I'd have him drop Louis, Marciano and Walcott but lose all by KO. For me it's Ezzard Charles at HW. I think he'd put to much fast pressure on Charles and would eventually take a KO.
Charles was arguably the best light heavyweight of all time and gave Marciano hell twice. Patterson had speed (and underrated power) but he was a very small heavyweight not that much bigger than Charles. I would favor Ezzard.
Imo he d beat Corbett Fitz Marvin the destroyer Hart Tommy Burns Jess Willard Jack Sharkey Carnera.. But what a war!! Braddock Charles.. Maybe Walcott.. Maybe Marciano of the Moore fight I believe he'd beat. That Ingo guy probably, but he'd have to watch for his right hand! Leon Spinks Michael Spinks.. Maybe Michael Moorer could be a close fight. Can we say Floyd could perhaps, just maybe beat old old Foreman of the Briggs fight? And that I believe is that.
Floyd and his bum of a manager dont have enough disquises in their trunk for floyd to fight the best ever
I could see him possibly beating Schmeling (it would be a thrilling war but Patterson edges it or stops him late), Weaver (probably has to get off the floor to win), max Baer (stays on the inside and outhustles him with body work avoiding baers looping shots), bruce seldon (8th round (KO), Bermane Stiverne, Tony Tubbs, and possibly David Tua (if he makes it a phone booth fight).
