4. Miguel Cotto
At first glance, it could be seen as a slight step down considering Canelo has already beaten Cotto. However the Puerto Rican warlord is still a huge draw and his valiant effort against the Mexican proved he still has a lot to give.
While he may not have a world title to offer, his name recognition and exciting style make him an attractive option. He is also closer to Amir’s size than Canelo and a fight – perhaps at super-welter – would be a fairly even physical match.
