Buncha Sherbabies have their knickers in a twist over this when it's really much more simple than they realize. DJ's negotiating tactic is to say he doesn't want to sign to fight TJ or Cody at 125 until he knows they can make the weight, so he doesn't waste his time preparing for a fight which wouldn't count as a defense if his opponent misses on the scales and which wouldn't take place at all if his opponent is pulled, like several fighters have been due to bad weight cuts. The UFC can easily mitigate this by having a standby challenger for if TJ misses weight, guaranteeing DJ a legit defense. They can also pay guarantee him his payday. If they do this DJ has much less reason not to take the fight. (I say "much less" rather than zero, because he would essentially have to prepare for two different opponents, TJ and the alternate, but they could mitigate this also by having the alt be a lower ranked opponent, and possibly one DJ has already beaten, and thus someone DJ's already prepped for before.) Anyone who thinks an 11-defense champion owes any 1-defense champion any kind of favour is a naive sucker.
