Are you kidding? His performance against Lennox Lewis was pitiful. Tua should have stayed in 'John Ruiz KO 19 seconds' form. Instead he got fat and slow.
Yeah, Hagler is hard to knock. Only thing you could say is that he made the mistake of trying to outbox Sugar Ray Leonard at the start of their fight
Gatti should have controlled his weight and stayed in the lighter divisions - he could have been one of the best lightweights of all time instead of being a human punching bag for the likes of De La Hoya and Mayweather etc.
