These guys are right.

Henry Cooper knocked him down. He was HUUUUUUURT. Precious seconds were added by the glove problem.

Close second is Frazier, in the first fight.... he had Ali staggering backwards, Ali played it more, but Ali was ready to be killed.... so he conned Joe that night, fooled him... Joe's trainer, Futch teased him about it later.... called it the "long walk" ..... had Frazier hit him once, he would have KO'd Ali
