I want to see Cotto against the best MW in the world, not a guy who already schooled him and doesn't even fight at MW.
Of course Mayweather won't be interested. He already beat Cotto decisively. He has nothing to gain from that fight. Cotto has some big fights in his grasp. He might as well forget about Mayweather.
Floyd gains nothing of beating overrated bum Amir Khan, the victim of Danny Garcia and Prescott, who barely won vs Algieri or shot Diaz
