Good question.
What Pavlik says but Cotto needs to look at the tape of the 1st Castillo fight to see how a limited fighter can impose his will on Floyd. Also the Oscar fight cuz for 6 rounds it was working ofr the old man.
Cotto doesnt have the speed or southpaw stance of Judah or Corley who both stated well but faded. Its going to have to be grit and determination cuz he cant look pretty doing it and Cotto has always liked doing it at his own pace.
