I think they should make it where the fighter must weight inside the weight class bracket. For example: I'm sure we all can agree that Pac can still make 135lbs if he had too. So since Pac is the the Jr. Middleweight champ, let's say he makes a fight with Marquez at 135 for the Jr. Middleweight title. That's possible right LOL. All they have to do is come at the agreed weight, anything less than the 154.
