Trilogy against Diaz or Khabib rematch. Of course he will get a title shot straight away. Dana juggles his bollocks in his mouth, and he is still the biggest draw for the UFC.
Let's not forget how good he is either. He's only lost to Khabib & Diaz in the last few years, he's still an excellent and unique fighter. The question is whether he wants to build a legacy, but he's probably too coked up to give a shit about that anymore which is a shame, cause he could have been a great.
