I don't think Pacquiao will KO Cotto because of the way Cotto hides his chin but I do think Cotto will get cut above the eyes for the same reason. I don't see them stopping the fight though because boxing's starting to get interesting again and that would just confuse a curious public. I think Pacquiao will win by decision. I think the fact that he's had three "easy" fights will actually work to his advantage. I think if Pacquiao fought a Morales 1 or Marquez 2 type war before this fight he'd get frustrated, eventually stand toe to toe with and get killed by Cotto. I think power will be the last thing on his mind. He'll be on his toes all night thinking speed, speed, speed in-score-out. As the fight progresses he'll land more combinations but a Cotto counter will keep him honest. I do think that if Cotto attempts to defend Pacquiao's straight lefts with the same shoulder roll parry he uses against left jabs he'll get caught by the same punch that hit Hatton later on in the fight though I don't see him getting KO'd. I think Roach has planned this. Plenty of speedy lead lefts like those used on De la Hoya early setting up the wide looping left hook.
