I've got that sick feeling in my gut that someobody will say Foreman. Please, nobody do that. Please.
:nut Sorry I don't mean he didn't have any standout performances in between, he had ****ing dozens of them, I am referring to his longevity, ie: he was able to turn in a standout performance vs a world-level fighter 19 years after his 1st one, which is remarkable. The guy who posted the Holyfield alternative got what I meant (although I'd argue that a close loss to Valuev is not a standout performance vs a world-level fighter IMO).
