So at WrestleMania 23, they say that the plan was to do a Tony Cena vs. Triple H rematch, but then HHH's quad injury necessitated them going to Plan B, which was Shawn Michaels. Do you or anyone remember what they were going to do with Shawn before putting him in the main event slot?
The logical thing seemed to be a three-way match with Cena v. D-X because they were teasing various things in that direction, but I never heard of a specific direction for Shawn otherwise. I would imagine he would have ended up as HHH's cheerleader at ringside, were I to guess.
