Is cotto's new trainer really a boxing trainer or is he like Joe Santiago who used to be a nutritionist?
He's worked with some pro's before but his claim to fame is that he is the main coach for the Cuban Olympic team. I think he has a Phd in something related to sports medicine or nutrition or something in this field.
I'm not sure of this. Here's some additional info on him though: http://www.fighthype.com/pages/content10929.html
