If Conor rushes to return, he will lose. He should not worry about trying to get back into title contention or rematching Poirier again. Conor will get paid no matter who he fights, so it makes no sense to wade back into the shark's tank right now.
He really needs to lose Kavanaugh and SBG. Surrounding himself by yes men and ass-kissers is killing him. All of his contingent and friends who are enabling him are simply riding his coattails and ruining him at the same time. As much as I dislike it, Conor could probably talk his way into a title shot at any time, and DW and WME will oblige him.
So why rush it? Pick some easy fights, or opponents that play into his style (ahem... Nate). Not saying Nate is easy, but Conor won't really have to worry about the grappling or wrestling aspect, it will simply be a matter of what gives out first, Diaz's chin or Conor's cardio.
If Conor can put a win or two together and find his drive (instead of his sales pitch), if he actually find his confidence and believe in himself, then Conor can get paid and approach this sensibly. Right now he's on autopilot... got to be the best, have to be the star, need to be in the biggest fights. He needs fights where he can shine. Whether it is at 145 or 155, he needs to ground himself and make it about the fighting again instead of the showmanship.
