Actually Michaels was in the NWO. The WWF/E brought back the NWO in the early 2000s and added Michaels to it for a brief moment in time, but the NWO was dead in the water by the time Michaels was in it.
Must have been a very brief moment because I don’t remember that. I do remember Hollywood Hogan continuing the NWO line long enough to face The Rock at Wrestlemania, and after that it was pretty much done completely.
