If you've forgotten the images, you can't forget Howard Cosell's voice that day, seemingly ill-prepared for what he saw in the boxing ring before him.
Time and again, young George Foreman sent heavily favored Joe Frazier crashing to the canvas, and all Cosell could say was:
"Down goes Fraz-ah! Down goes Fraz-ah! Down goes Fraz-ah. . . ."
Foreman knocked Frazier down six times in 4 minutes 35 seconds, winning the heavyweight championship in the second round.
Years later, he said the savage beating he gave Frazier that day in Kingston, Jamaica, was forged from fear, not confidence.
His trainer, Archie Moore, had decided on a game plan that began at the weigh-in.
"Archie wanted to make Joe angry, to upset him, so he had me show up an hour late for the weigh-in," Foreman recalled. "He felt it would make him so angry, it would affect him in the fight."
