all he did after missing 3years of his physical prime was come back and beat joe frazier and ken norton two out of three (the loss to norton he fought the majority of the fight with a busted grille), knocked george foreman out when george was in his prime and seemingly indestructible (that was after ali had already lost to frazier and norton and was thought to be thru)

he also had wins over quality guys like floyd patterson (twice), jerry quarry (twice), cleveland williams, ernie terrell, oscar bonavena, george chuvalo, ron lyle, henry cooper (twice overall--once pre liston, once post liston), jimmy ellis, zora folley, buster mathis, joe bugner (twice), chuck wepner, and jimmy young (who ended foremans first career with a legit win over him remember).

oh yeah and rocky marciano beat --in his absolute prime mind you ---thouroghly washed up versions of joe louis, ezzard charles, and joe walcott---oh and dont forget thoise world beaters donny cockell and roland lastarza---two househole names

marciano wasnt good enough to be ali's towel boy............
