Can Mayweather KO Pacquiao?

After having watched the Cotto fight, im wondering whether people do genuinely believe if Mayweather is capable of KO'ing Pac. The video in the link is a good highlight of the Cotto fight, and Pac really does eat some big punches (watch on from 1:35 and he gets cuaght with a particularly monsterous uppercut), but he doesn't seem phased in the slightest.

Now before I get slated for being a *******, I'd just like to say that I pick Mayweather to win by controversial SD. The entire point of this thread is to establish, based on the Cotto fight, if May is capable of delivering a KO.

Thanks

Thanks for responses. I agree that he can KO pac, Broxi mentioned that May can hit you with shots that you just don't see, and I think that's spot on.

I'm just hoping they are both able to bring out the best in one another. I don't think we've seen either of them at their peak as of yet, they seem to dismantle opponents with consummate ease and I think the only ones capable of revealing their best, are indeed the 2 of them, and perhaps Mosley.
