True, but the UFC would easily replace him in a heartbeat if they could make Khabib fight anyone else for the interim belt.
He isn't playing anymore games with the UFC. He wants the interim title, and the best match up for him outside of Diaz is Tony.
Nate knows if he waits long enough he gets Conor no matter what, because he's an easier matchup than Aldo/Khabib and he's a bigger draw than Tony. Eventually McGregor will be forced to find a matchup he doesn't like or... fight Diaz again. He'll pick Diaz. Aldo doesn't give a fuck who he fights, he just wants to force Conor to rematch him.
