A few things:
1) Cotto vs Mayweather would be a very good fight BUT it would be like the one we saw on May 5th. We all know what Floyd will do, throw 1-2 combinations ( very seldom ) and use the right, right, right, right, right, right, right (one punch at a time). If Cotto walks through these, like I think he would, it's bye bye Mayweather because it's going to be like Castillo on CRACK!!! Cotto doesn't tire easily and he can hurt you to the body. Unfortunately, I don't think Mayweather will get KOed since he will RUN like never before once he's hurt.

2) Cotto vs De La Hoya...Prime De La Hoya beats Cotto in 3 rounds. The 34 year old DLH beats him in 8, are we forgetting Oscar does well against fighters that charge him? If that left hook lands ,and it will since Cotto's defense is average at best, it's BUENAS NOCHES senor Cotto. This would be a GREAT fight though. I still wouldn't count Cotto out since he WANTS to win every time. If Oscar uses his jab more than the Floyd fight he wins in less than 8 rounds.
