I don’t like Frazier’s chances for the fact he bobbed straight into uppercuts at his waist that would always hold him back against a lot of the best fighters IMO… but if he consistently gets in with a little luck or the right plan he’d grind Tyson down (any version) he looked horrible trying to navigate inside where Frazier was right at home - if you had a ref who liked Tyson and broke it up every time he went to work he’s screwed.
I say Tyson by stoppage. Iron Mike was faster and more explosive than Frazier. Joe had better stamina and could have won if the fight had ended on points but I think we would have seen a furious battle from the inside in which Tyson would have won, even tasting Frazier's left hook.
I have 55/45 for peak Tyson to beat peak Frazier. However, in '91, Tyson was still in his prime, but not at the absolute peak, so I go for Frazier by late TKO here.
