The reason why he pulled out of the fight with poirier was because poirier wasnt about starting drama. He was being too nice and didnt want to say shit. Nate wants to hate his opponent. Gives him a reason to fight. Gets the fan interested as well. Pettis is about that life when it comes to Nate. They have beef from the past. Not only that but he probably sees himself piecing him up at boxing range the entire fight.
