I honestly would go for Pac to beat Cotto. Fair enough Cotto would have the size and he is a good boxer with good speed but Pac is a better boxer with better speed and a freakish ability to carry power if not improve it the higher in weight he goes!

I think that Pac would T-off on Cotto and stop him late like Margarito did only without taking the punishment Marg did first.

I really don't see this fight happening though unless Marquez beats Mayweather but I don't see that!
