Oscar's jab was the most overrated punch in the fight. It hardly landed at all. SUre it did a few times, and thats bound to happen, but it wasn't dominant in any round except maybe the 7th... people are totally overhyping what Oscar was doing. And as for Oscar's defense, he definitely made Mayweather not land as flush of shots as he would have liked, but Floyd still landed a very high % of his punches. As for all round fighter, both this Oscar and Cotto are pretty close, Oscar is a superior boxer, Cotto is a better pressure fighter, Oscar is harder to hit, Cotto is more accurate, both hit hard, but Oscar has a way better chin, both have troubles down the stretch when they are being pushed in a fight. Oscar's faster, Cotto has better timing, but after that Oscar is a lot bigger, more experienced, etc, etc.

Cotto does have a chance, but not a very big one, and no Oscar stood no chance against Mayweather.
