Pacman has gone up, but made the bigger guys to come in under their division limit. Bearing in mind how tough the JM Marquez fights were, how would he do in catch weight fights v Katsidis, Gamboa or JM Lopez? His main asset 'speed' would be negated against the smaller guys, but would he punch through them?
He'd be weight drained at anything below light-welter. Even still, if Gamboa and juanma go up in weight I don't see how they'd pose a problem with a guy who's been dealing with big welterweights. Marquez vs Pac at 140 is very interesting IMO.
