George Foreman's come-back was also rather spectacular some years ago. But I somehow have the impression that since boxing in general is in decline, modern "top" fighters are not anywhere near what they used to be some decades ago.
I have heard "ad nauseam" the argument about an hypotetical Muhammad Ali vs. Mike Tyson engagement....most people I have heard were sure that Tyson would have been able to knock Ali out, and the argument was the KO record Iron Mike had. But few did know that Ali finished a fight against ken Norton with a broken jaw. So I guess Norton -and other boxers of that time- did hit as hard -or even harder- than Tyson, as Tyson has never broken anybody's jaw (Though he has ripped off an ear

).
Interestingly, no one less but the mighty Joe Louis suffered a terrible come-back, where he wasn't anywhere near his former performance. Certainly, the come-back was in a moment of economic pain and probably not as well-prepared as he would have liked, but anyway, those were different times:hmm:
