I hear you but that's not enough of power to hurt Holyfield. Ali only had that good 1-2 combo (jab followed by a right). He threw slapping hooks like Calzaghe!
We know Ali was a "freestyle" fighter, he always kept his guards down.
Holyfield was a great counter puncher. Ali had trouble with classic type boxers like Ken Norton (who broke Ali's jaw with a left hook).
Ali always got caught with left hooks (like the one he caught from Frazier that knocked him down).
Riddick Bowe knocked Holyfield out in their 3 fight and was the only one to knock him out to my knowledge. After that fight it turned out that Holy had hepatitis or something like that. He was gassed.
I could see Holyfield knocking Ali out though.
holy had more heart than Ali.
