Even if he can he would'nt find who to fight with! Maybe Quinatana who mentioned something about a rubber match!
I wonder what would happen to his punch resistance if he tried to go back to 147? The brain is surrounded by cerebral-spinal fluid, and that is part of what protects the brain from slamming against the skull. Dehydration diminishes those vital fluids, and punch resistance suffers. Put that together with PW's now well documented trouble with fast hands, factor in Nazim Richardson, and you get Mosely TKO Williams.
I don't think he could make 147 well anymore, but the guy's a freak so we can never be sure if he's bluffing or if he can actually fight at welter and not be drained.
What was his fight night weight against Martinez? I honestly don't think he can make 147 without suffering a whole lot in the process...
147 is his optimum weight...seriously, in an interview he's said the highest he'll ever walk around at is 165, he was 166 tonight and you could tell he hadn't quite brought all the power up the ladder
