If I'm him, I by my time long enough, and win a few fights, and wait for the winner of Aldo/Conor, and get in line for the title shot. If he beats Holloway, and Conor wins, he should for sure get the shot. If Aldo wins, he could still fight Conor.
In fact, I think he should fight the loser of Aldo/Conor, and if Conor's the loser, big pay day for him. Basically, just try and get that big money fight with Conor, then move down, or retire. He's done it all, and doesn't need to fight anymore. Of course, he's still got a ton left in the tank, and if he feels good and healthy, why not keep collecting pay checks? He's still got a lifestyle to maintain, and hopefully he gets a gig with FOX, or some type of analyst job for the UFC.
