Cotto beating Margarito was about nothing else other than exorcising the demons. What that would have done for Cotto mentally is priceless.

Mayweather has faced good guys lately. Marquez is an absolute warrior but he was too small, his heart and skills were not going to make up that disadvantage. Mosley is a name, but was there to last the distance. Ortiz was a good live opponent but he fucked things for himself before the fight really got started.

Cotto's fights have been confidence builders, Mayweathers have been money makers.

It's hard to predict this fight really as we don't know if Cotto has much left. Also Mayweather fights so infrequently and he is at an age where the activity can creep up on him.

We can't deny that on paper it is a very good fight.
