Well, Pacquiao DESTROYED DLH who shows he was a very good champ at 160. How does he fare with Roy? Roy never fought anyone as fast as Manny and Manny seems to get more powerful as he goes up in weight, I say Roy is unable to deal with Manny's skills and his chin gets exposed!
Roid ruined himself coming back down to light-heavy. If he dropped down to 160 now, Pac would definitely beat him
