Lets keep in mind that he was also a shell of himself when he fought Holyfield and Lennox. No head movement, no trainer that knew his system and was doing hard drugs most of that time and looking for a way out.

He didn't get popped for weed while driving around and buzzed by a flabby frenchman, or chubby heavyweight while enjoying a 4-7+ inch reach advantage and flailing cuffs. Easy to talk trash when your in an era of subpar heavyweights.
