Roy Jones became HW champ then had to lose lots of muscle mass to compete again at LHW. It killed his body and journeyman Tarver ane Johnson KOed him. Roy never recovered from those losses and his legendary cat like reflexes were gone. Looks like Conor's weight cut time is even shorter than Roy's. It might be Conor's biggest mistake career wise. Don't be surprised if Aldo KOes Conor.
