Did Cotto lose alot of his power or has Manny's chin got that much better?

Cotto gained a lot of his power from the WAY he threw punches, when throwing his power punches he often threw as if hitting a home run, usually with full torso, back, ass and legs into it, and would do this throughout the fight until he would break his opponents down.

Like i have been saying for awhile now, i havnt seen cotto throw the same kind of hooks since the beginning of the mosley fight, or gomez fight, and what he throws now are essentially powerful arm punches. (his hooks im talking about)

so its not that his power deminished so to speak, the way he threw his punches did, and thats what imo has diminished. He is still a very solid puncher, but he doesnt imo have that break you down power because hes not 'hitting that homerun' so to speak. Hes much more stiff.

His jab is as good as ever and his right hand id say is as good as ever, pac just has a really good chin. I think the type of chin Pac has you need to have very good speed and catch him JUST RIGHT in order to really hurt him, especially now at a higher weight.

Pac has a very, very very good chin. The only person i think could hurt him now is mosley and maybe holt/torres if they landed a cracking shot, but they would get beat to hell anyways (holt,torres)
