What are some fights where if it went one more round, the loser Wins?

It wasn't that simple. Ali likely would have forced himself to come out, he was that type of fighter, and he could have killed Frazier if he came out for the 15th. Just a possibility that the fight might have gone the other way if the 15th happened.

That was Ali's toughest fight, he wanted to quit at the end of the 14th. Dundee told him no.

If Frazier would have come out for the 15th, Ali still wins, Frazier could hardly see was in just as bad shape as Ali and well behind on the cards.
