I may sound harsh when I say this, but he didn't offer much in terms of AEW when it has come to his wrestling. Old school gimmick, can work, but in a roster where, even early on, had The Elite, Moxley, Darby, Sammy, Jericho, MJF, Riho, Shida, Nyla, Dustin, all of them I would prefer to watch. And I'd argue that when it has come to his storylines they were not really great. QTV hurt Hobbs, though could be a lower card heel group. The Factory and their storyline in the Codyverse hurt him, hurt Ogogo, hurt Cody. Then he faced Paul in a match which was a Squash to put over a legend which only really served as a pallet cleanser before the main event of one of AEW's best shows ever. I think it is just a case of someone who is better as a coach than he is as a wrestler. And no, I'm not saying he's a bad wrestler, but I mean there was no real "Wow" factor to him as a wrestler on your roster even though he's well rounded. But he's got so much knowledge he's an excellent coach.
So I think them separating is the best outcome for both.
