I would have preferred Conor to fight someone else who has been training for a fight. Who knows what kind of Nate Diaz we are going to see in the cage.

My guess is that they picked Nate figuring that if he wins, he'll probably fail the drug test, thus saving face for Conor.

Plus they know Nate can help sell this fight with his mouth even though he isn't the most worthy opponent.
