So thinking where these people could possibly go:
Kalisto - The potential hidden gem WWE really missed the boat on, IMO. I think AEW will run to get him, BUT it wouldn't shock me if he ends up doing something Andrade wherever he ends up.
Billie Kay - Personally, this release hurts the most. Billie Kay has comedic timing hardly anyone in the business has, and while not great in the ring, would be a great manager.
I'm guessing AEW gives her a look (her and Britt Baker could be pretty hilarious), especially since she's friends with some people there, and they don't mind managers. And to be honest, AEW needs more personalities that stand out beyond being good in the ring.
Chelsea Green - The potential is there, but yeah, it's kind of tricky. I'm guessing the obvious with returning to IMPACT, especially since Ryder is there.
Mickie James - IMPACT is the obvious option with her history there and to make a deep division deeper, and she'd probably have more screen time than if she went to AEW.
That being said, I think AEW really needs to give her a look, because she'd be an amazing vet to have around.
Tucker - NWA or ROH. Seems like he's got skill but he's got to build himself to be someone people will care about.
Wesley Blake - Really feels like ROH is possible, build himself up, and become relevant in some way.
