We already saw Castillo outpoint him and since then he fought past prime guys for their popularity. Gatti, Hatton and De La hoya are good examples of this.
^^^ Hatton was 'past prime'??? WOW.... Oh that's right, he was only 43 and 0 coming off one of the bigger wins in his career... never mind.
no orthodox fighters at this point can defeat him. He's just too good for his shoulder roll defense. but an awkward sothpaw who's as fast as him, hits harder, high workrate fighter who throws insane combos and never gets tired will do the trick for him.
Very diffcult to beat? yes. Is he unbeatable? no. No one is unbeatable even in their primes. I don't think there is a boxer today in the 140-147 range who can pull it off.
****ing aye! tyson's demise is a POSTER CHILD for anyone who thinks mental wellbeing isn't key to being a complete fighter. tyson imploded. the first person to ever beat mike tyson...was mike tyson by default.
