I think catchweights effect Manny's fights. I don't whether it had a negative effect on Cotto though. Until the uppercut, if anything he looked faster and sharper. I don't know if his chin was effectced too because he got straight up after the 1st KD and the uppercut was just perfect. He also took some very hard punches later on which could have put him down. However, I felt that his power was slightly lower though this may be due to him deciding to throw more punches in bunches. The combo where he landed the uppercut between Pacquiao's gloves (I think it was a left hook to body, left uppercut to head, overhand right to head then left hook to head) was beautiful as were the body punches he threw after defending Pacquiao's left hook? to the body.
