If Shane wins, it would have to be by KO/TKO, because with Pacquiao's workrate, there's no way he wins a decision. I still don't get why you believe that Mosley is such a hellacious puncher, most of his KO's have been the result of an accumulation of punches, not a single shot. I mean yeah, he caught Mayweather with a decent shot, but I think Floyd was more surprised then hurt, by the end of the round he was in control and firing back.

The thing is, even if Mosley does catch Pacquiao with a big shot, he should be able to take it, he was hit with some big shots from Cotto and Margarito, and just kept on trucking. And Shane is not going to be able to stop Pacquiao with an accumulation of punches, because he's not that easy to hit, and Shane is going to be too busy trying to block the vast array of punches coming at his head.
