He also said that McCool did the "Faithbreaker" better than Styles does the "Styles Clash". Just because he has the independent say to run his mouth on RAW and Smackdown tapings does not mean what he said is true. In fact most of what he said in his promo was bull sh**.
Probably because Kane was still kind of an active member of the roster when AJ debuted in 2016. He was referring to AJ sneaking into the WWE when all the guys he mentioned were gone. Still an idiotic argument but its a promo and the delivery was good so who cares.
