It is not hypothetical that they were at the best point in their careers when Marciano fought them. It is obvious Joe Louis was past his best, but he was far from being completely shot too. He was still a very relevent contender when Marciano knocked him out. Moore and Walcott had never seen better points in their careers and were putting on consistently good performances when Marciano knocked them out.the points u make are al hypothetical. how can u possibly say guys like louis, moore and walcott were not past their best?? they were in their late 30s...not even modern day athletes are at their best let alone boxers. specially in boxers from rockys era who would have fought many hard tough ring brawls. guys like moore and walcott..their bodies were battered and bruised. and on the point of ali not being modest, he often described floyd patterson as the most technically skilled fighter he ever fought, sugar ray robinson as the greatest fighter he ever saw. frazier as the greatest fighter he ever fought... much of what he said was hype in his younger days...as he got older and matured he became more serious during interviews, only coming out with jibes against other fighters for comedic value. and i just want to say ali at his peak would have destroyed marciano..maybe no KO but marciano would have been mentally and physically destroyed by the 15th..if the fight wasn't already stopped.
