I think it revealed a weakness that wasn't tested pre-prison: that he couldn't go the distance against the very best in his division. Holyfield and Lewis weren't in their prime either.
I just don't buy into the Tyson hype, never will. Name one top tier fighter that he ever beat, don't say Spinks, I mean best of the best, it never happened. It's a tough call but I like Jack Johnson and Clay
