Pac really doesnt look undersized.
Technically you could say Hopkins was the smaller man when he beat the snot out of Tarver. Funny everyone points to Trinidad and Wright(both fights he was supposed to lose) when they say Hopkins only fought smaller opponents,but nobody points to Tarver to say he beat the snot out of the technically bigger opponent
Tarver was champion at the time and everything.
I like Hatton more then Pac admittedly,because I like brawlers,but I dont think Pac's size will take anything away from it if Hatton wins,and honestly as slick as Manny is I wouldnt place bets either way.
