Cotto wins by destroying Khan's heart along with his chin. No way the fight would happen at 147lbs. If Cotto wouldn't drop back down to welter for a big pay day to rematch Pacquiao he isn't dropping sown for Khan. Even at a daft 150lbs or so catchweight he smashes Khan. I actually think Team Khan are daft enough to take this hypothetical match up if it were offered to them. Khan has seemed convinced in the past he'll retire a three weight "world" champion and that his "power" will carry to 154lbs. Numpty.
