This is by no means a rebirth. He did what he was supposed to do against a level b journeymen. I hope he stays at 154 because he is not a middleweight and would probably get knocked out against Sergio which is the fight Arum is trying to make. If he wants 1 last payday then go ahead and fight Canelo or Martinez. If he wants to stay in the sport awhile longer then fight Carlos Molina for that other belt.
