How many times would they have to fight before Frazier finds a way to get to Foreman, and is this presumably 100% impossible given the outcome of their 2 fights? Frazier did manage to last into the 5th round I think, much much better than their 1st encounter in Kingston, Jamaica. Could Joe have found a way to take it a few rounds more until George burnt up all his fuel? Or what else could he have tried?
