Cotto may not hit as hard with 1 punch to the body like Hopkins but he hits the body way more and at 147,his left hooks are destructive. He would break Oscar down. He also has a good jab,and I don't think Oscar is that great at dealing with jabs,he's too straight up. Oscar's chance would be to land the left hook but if Cotto prepares throughly,he should be able to avoid it and without the left hook,Oscar is half the fighter. Cotto via points/late stoppage.
