Cornette has been saying this would be a problem for years. These deathmatch indy junk wrestlers were always a potential problem waiting to happen. That's unfortunately one of the legacies of ECW... it popularized death matches to people without the actual talent to really wrestle. Hopefully the backlash won't effect any of the more legitimate wrestling organizations.
And hopefully AEW will be a bit more careful in the future. I would hate for this to effect them.
