because Floyd has already made 3 excuses everytime Cotto's name comes up. When Floyd's name comes up for Cotto he says sure I'll fight. And when Cotto's name comes up for Floyd he either makes an excuse or says hes going to retire like a little *****. Go figure, If you think Cotto doesn't have the balls to fight ****ing Floyd Mayweather you're delusional. And thus if Floyd would just say just like Cotto says "sure I'll fight" then this **** would have been made a long time ago. The Cue from Cotto to Mayweather = I want to fight you. The Cue from Mayweather to Cotto = **** off and fight someone else.
