Arthur Mercante Sr., the ref for that fight, would beg to differ. The first Ali-Frazier fight did indeed take a lot out of Frazier, and probably represented Frazier's peak. That being said, I think a peak Frazier still gets knocked out by the 1973 George Foreman. Just maybe not in the second round.
