I don't think he needs to run all night, he'll need to move some but more than that he needs to beat Cotto to the punch and then turn him, just move to the side, not straight back. Cotto's not the quickest guy on his feet, he can be out manuevered IMO. The thing is (and I hate to quote Teddy Atlas but I think it applies to this fight) Cotto can make some mistakes and get away with it, Paulie probably won't be able to get away with it, he really needs to minimize his mistakes.
