Lets not get crazy.
Yair Rodriguez has kicks and cardio in spades. Those are his only weapons, really, and he uses them indiscriminately. Yair will have a short shelf life unless he really changes his game, because his style will not be physically sustainable in another few years.
Conor McGregor's distance control can win him this fight fairly easily, in my opinion. Once inside of the kicking range, Conor has 3 inches of reach on him. Yair lunges with his face ahead of his fist on punches and Conor, above everything else, lives for fighters who close the distance face-first.
I see an easy KO for Conor at this stage, unless Yair lands a lucky kick.
If the fight happens in a few years, Yair won't be able to do what he does now anymore.
