Dude. He refused the fight.
He literally. Fucking. Refused.
Also demanding *TJ's* purse if TJ missed weight is just a crazy radical demand. Demanding crazy shit is a method of ducking.
You can say that MM refused the fight offer, the UFC then refused MM's crazy demands and issued a modified offer, and MM then refused that offer. But in the end, however you slice it, MM refused the fight with TJ that was offered. This happened.
And I will say again - I think MM was correct to duck TJ. TJ wasn't champ, and a much higher risk fight than Borg, for the same pay. I think ducking TJ was the right move by MM. He has to do what's best for MM. Not what's best for the UFC, or the fans - what's best for MM.
Now that TJ is champ though, it's less clear if MM should duck him again, from MM's POV.
