Prime for prime which one of these fighters would have prevailed? Ali beat Foreman because he out thought him rather than out muscle him. Considering that wasn't the style of Marciano. Would he have KO Foreman or would he had suffered his first lost by KO?
I would pick Foreman to be able to relegate Marciano to a low form of which we never saw from him. So much range to close and Foreman's power is no joke to any pressure fighter... It'd be weird seeing Marciano move backward and I don't think he'd do it well, especially giving up size.
Foreman easily beats Marciano. Marciano looked good beating up 50s LHWs/CWs. Not so vs. a genuine SHW.
General consensus among most students of boxing Foreman would have been possibly the worst matchup for Marciano of any top fighter in history. Same reason that Joe Frazier was, big tall power guys with any kind of chin at all will beat the swarmers almost everytime. Although I think Marciano was better than Frazier, primarily because he had two powerful hands unlike Frazier, he'd still go down. Marciano would probably still be trying to take Foreman's head off after the seventh knockdown, but eventually the fight would be stopped.
It depends. If George is allowed to push Rocky the whole fight like he did against Frazier than its an easy win for George. But, knowing Rocky he would most likely start fouling George back to even the playing field. If Rocky can get around George pushing him away I think he wears down George and stops him late.
I think it's fair to say if Foreman doesn't blast Rock out of there early he gets ktfo'd late by Rocky
