They've already done that: The stipulated weight you have to make on weigh-in day itself limits the weight someone can cut. Nothing more is really necessary, as this is not really a problem. The Paul Daleys and Rumbles of the world are the exception, not the rule. Other then those kind of guys, this shit only comes up when moronic people on forums like these want to discredit the success of a fighter.I think they should put a limit on how much weight someone can cut for a fight
