He was 148 against Soto even though he was in at 128 something. Doing this to your body can make it so that you can't even even get within 10 pounds of that down the road. Obviously he was destroying his too much in order to make 130, and sometimes that makes a guy skip a weight class. Thats why Castillo had a hard time making 140 after fighting his whole career at 135, and thats why Corrales skipped the LWW division, because he couldn't make 140. When Guzman is putting on 18-20 pounds from weigh-in to fight night, that will have its a toll on a fighter even if they don't go through wars in the ring, that doesn't mean their bodies haven't gone through wars in the sauna. If he still turned down the fight, and the chance to lose the weight it tells me something was very wrong with him, and that to do so would be very dangerous.
