Are we only talking about opponents who Tyson fought BEFORE he fought Douglas? Because if that's the question, then my answer would be ZERO. Tyson was off his game, but he still would have beaten guys like Bruno, Berbick, and Thomas.

People forget that the Douglas upset didn't just happen because Tyson was at less than his best, it was also because Douglas was in phenomenal shape and fought an incredible fight.

Douglas could have defeated any heavyweight in the world on that night.
