My question is how do Mosley and Cotto pose more difficult tasks for Mayweather? Mosley throws combinations, but these days their are more like Calzaghe's combinations and less like the ones Shane threw as a lightweight. He doesn't fight at the same speed as his body moves at which was evident against Cotto who beat him to the punch repeatedly. Miguel Cotto is a great fighter, but he has slow movement and Mayweather is Zab Judah or Paulie, he is a lot harder to hit, and he hits a lot harder than Paulie. We saw Floyd take Baldomir out of their fight in the first 4 rounds because its so frustrating to fight him, while Baldomir never lost hope against Judah because if you keep coming Zab will eventually fold. Once Mayweather doesn't use his tradional defense against southpaws, he has more of a peak-a-boo defense and Zab was able to split his guard with the left hand at will, not only that but Floyd is very squared up against southpaws so its easier for Pacquiao to land his right hook as well.
