Tough one to call imo. Cotto has been wobbled by lesser punchers than Roger. It's easy to see one straight right hand changing everything. I like Cotto in this one though. He could get inside working Mayweather's body over. Miguel would get tagged for sure, but not with the one big one. Cotto UD
Roger was pretty good at 140. He had speed, skills, and his right cross could put Cotto in SERIOUS trouble if he landed it, but I think Miggy breaks him down and stops him circa 11. I THINK.... but Roger is pretty live.
