Death to the Mexicutioner...haha just kidding Pac would have a better chance than the weight differance would suggest. Pound for pound Oscar doesnt punch as heavy as some of the fighters that Pac has faced in the lighter weights, namely MAB and El Terrible. I think both of those guys hit harder than Oscar in their respective weight classes, and by going up in weight Manny will be able to absorb the punches better as well.
