Diaz will take cotto like a sharp knife thru Margarito, Mayweather and Pacquiao.

Diaz the well known cuban trainer that was in charge of the cuban olimpic team. got the numbers of Margarito, Mayweather and Pacquiao. this guy hardly talks, but when he gets in his office he watch every fight of cottos next fight ten times. he look at speed, angles, power, legs movements, shoulder rollings. in fact this guy will know you better than yourself. when cotto destroyed margarito, he said "just go around and around, this guy is a sitting duck. just use the square and draw the pythagoream theorem on them and thay are yours. nice philosophy.
