Chuvalo gave Ali a pretty good beating to the body even though Ali was the clear winner in that fight. Ali spent some time in the hospital after that fight apparently suffering some internal bleeding from Chuvalo's shots. Late 60's Ali didn't hit as hard as the 70's Ali, and I'd bet on Frazier putting the 1960's Ali down on the canvas once or twice early in the fight. This version of Ali could win a decision over Frazier, but I'd bet on Frazier's pressure to give Ali problems any time in their careers.
Sorry, Im not into dudes and there will be no pulling unless your a dick head......I dont think Ali fought anyone with stamina and and power of Frazier, before the comeback Cooper had a fast hook, Doug Jones had speed but Liston was slow as missisipi Mudd...its not so much as speed that got to Ali but guys that would keep punching....Who did Ali fight that could compare to Frazier for power and stamina and youth before his comeback
