I would say Cotto was certainly not drained, although you can't tell about the inside, he looked great.

The beating aside, in patches, he boxed Pac easy, he just could not keep that pace and deal with the ferocity with which Pac went about his business. I certainly think Pac's power has been really underestimated too man, atleast from my side anyway. I got the fight totally wrong for sure, but, in patches, Cotto landed some flush bombs and Pacquiao just didn't even wince, he just either shrugged or smiled and carried on blastin.... Wow....
