Ali began to look like shit in his 2nd Frazier fight, about 1975 I'd say. George Foreman would have killed him in a rematch. Joe Frazier won the Thrilla but he couldnt see so he quit and lost. Ali refused to go out for the 12th, and Dundee and Bundini Brown literally shoved him off his stool into the ring. Jimmy Young beat Ali. Earnie Shavers beat ali. ali was shot to shit after the pounding in Zaire and really, frankly, shot to shit after the 1st Frazier fight. Joe Frazier crushed-in Ali's skull on the right side of his head that night, and it never recovered, ever, ever again.
