I think one of the things that AEW did best concerning Jon Moxley (Dean Ambrose) was how they demonstrated Moxley is a wild card type character etc. The WWE would proclaim "Dean Ambrose is lunatic fringe" repeatedly and never really give us anything to sell it beyond him doing things in ring that any of their stars would do. Like how they would claim how crazy someone is repeatedly yet we never see any type of that to make you see that.
So AEW his 1st night in did the SHOW...not TELL act. Which the WWE really never could do.
