PBF could and should fight at a catch weight but Cotto and Mosley can not make it at a catch weight. They would be drained as they barely make 147. Plus, if Pac don't want it with either Cotto or Mosley at 147 then they should say screw that and fight the rematch. Force Pac to fight welterweights at welterweight. That is what PBF has to do. PBF is a small welterweight so he should fight the catch weight. But the Pac/Mosley at 147 is Mosley all day.
