One thing that people fail to see when they try to show Floyd's weaknesses by referring to the cotto and maidana fights is that both of them are pressure fighters which don't rely on speed but making you uncomfortable, and also that both are quite a bit bigger than Pac. Pac will not be able to push Floyd to the ropes like them nor does he even fight in that style.

I would say that the best argument you could make would be referencing to the zab fight because their styles are a bit more similar (although definitely have differences). But Pac fights more of the jump in and out style like zab tried to do with Floyd. The difference though was that Pac has slowed a lot and is no where near as quick as zab was.

It's possible that Pac can catch Floyd but it has been possible for all of his opponents to do it too. I've said it before and I'll say it again, Pac may be the best fighter Floyd has ever faced, but it definitely won't be his toughest fight. I can't see Pac winning more than 3 rounds.
