There is no way that Hughes can cut to 155 in a healthy way. He would have to lose a ton of muscle mass. If he feels like he needs to change divisions, hes better off going up to the pretty weak MW division, where he actually would have a chance of beating some of the top guys like A Silva (because he has a good style match against him). Of course he would have no chance against guys he might not match up well against (like Hendo), but at this point hes just not going to be able to take all comers in any division that he can make weight in IMHO.
Consistency is the defense of a small mind
