AEW is a confused thing.
Cody obviously wants to bring back WCW. The shows on TNT, the ring and colors, the pyro the nostalgia acts, Bash at the Beach etc. So in that sense bringing back Sting to hit the old fart WCW nostalgic fans makes sense. But to have him around like Tully or Arn or DDP since they’re synonymous with WCW. Only way I want to actually see him wrestle again is if he has a flat top, even if grey, lots of TRT pulsating through his veins, and some neon Green or Pink tights or mix of Crow and Neon Sting Shining Wizard would be interesting. He can fuck off with that regular old Crow Sting though. Wouldn’t care.
I’d say use him to get a face painted guy or Road Warrior looking Team over or something. Having him around makes it seem more big time if they did something like that. But having him wrestle Matt Hardy in his crow outfit and balding long hair would be sad.
