I think pacquiao would stop him, guzman has the skills to out-box him but he gets drawn into a fight too often and fucks around alot in the ring. If he slows down and lets manny get to him in the same way that barrios did in the later rounds, it's lights out.
i don't like guzman at all, i can't stand his style, he too has a style like malignaggi where he has the "ass out defense" where he backs up all the time shuffling backwards with his ass leading the way bent over so all there is is to hit his back or the back of his head.
but i think with his style (that i can't stand) could frustrate pacquiao and he could win. he's a bigger guy and has skill, he has a safe defense (that bugs the hell out of me) but it works.
i think he can beat pacquiao, but also i think that manny could beat him; style wise i see guzman winning..........
