Of the top five listed in the opening post, I'd say in retrospect that Foreman TKO'ing Frazier shouldn't have been an upset at all. If Frazier was favored, as it appears he was, it was a major gaffe by the odds makers. This is one where Frazier would've lost 100 out of 100 times against Foreman. He did get knocked out twice, as he probably would have the other 98 times.
