Agree that Foreman was a monster. But Ali figured him out. The question is are there other iron-willed and iron jawed and/or creative guys in the ring who could have handled him?

1902ish Jim Jeffries was as big and powerful as Foreman and was accustomed to taking blows from five ounce gloves without a mouthpiece and going 20 rounds. Woulda been a war and the question is would Foreman's stamina have held up.

How about a guy like 1960ish Liston? That jab would have been a threat wouldn't it?

I guess I don't really think slick, smooth guys like Tunney or Loughran or Walcott make it 15 with George.
