Out of the choices listed I would say Wyatt, Ambrose and Sandow when they actually give him some promo time. If managers are allowed I'd definitely have to include Heyman and possibly Zeb too.
That guy has some irrational hatred of AJ for some reason. It just makes him look stupid in this type of scenario. Not being able to admit someone is good at something, when they obviously are, just because you don't like them is just diminishes the value of that person's opinion.
She can, but if you wanna cut a promo, you need a storyline.
