Hardly. Manny's speed helps not only his punching, but his movement as well. He gets away with a lot. Cotto has tremendous fundamentals and general ring IQ. Problem I see is that Manny will always beat him to the punch if both were to place the same technical move.
Pac vs Cotto 2 will be different.. Pac will stop him quicker this next fight. If this fight happens, then Pac is a joke.
