For both Mayweather and Cotto the longer they wait for Canelo to get established the more money they make when they fight him. A pre-Mosley Canelo is nothing like the same size fight as Mayweather. A post-whoever he fights next Canelo is an established PPV fighter with a massive following, provided he wins of course. He's going to make much more money for Floyd or Cotto then. Floyd doesn't have too many fights left in him and I would guess he wants in reverse order Cotto, Canelo and Manny. Who else is going to match the kind of numbers those fights could make?
