Its funny that people are complaining about Mayweather fighting Oscar when IMO Oscar beats Cotto more often than not. He is faster than Cotto, especially in his footwork. Oscar also has that great left hook and jab which Floyd nullified both in their fight. There are a few things that Cotto does to better, and he definitely fights a whole 12 rounds better than Oscar, but I see his slow pressure being a perfect style for Floyd to have his way with. I think Mosley getting hit over and over by the overweight, lethargic Vargas is the perfect example to demonstrate Mosley isn't, and has never been the defensive wiz that Mayweather is. Mosley is a sueprnaturally blessed athlete, but his skill level is way below that of Mayweather's, and his speed in general isn't even close to that of Mayweather's quick snappy punches will have more effect than Mosley's clubbing punches on a guy like Cotto.
