How would Warrior think he was a similar sucker to three things that hadn't happened yet?
Luger has always said that from the beginning, Vince told him that *if* he won the title, it'd be at Mania 10.
I doubt the PoP would have cared about the tag titles. They were happy to not have to take a scaffold bump every night. Crockett going into bankruptcy would have only further validated their decision to leave when they did.
Sid didn't even want to be a babyface, so he probably welcomed it when/if Vince "gave up" on it.
The bottom line is, the only sources for this story is one wrestler of dubious trustworthiness and wishful thinking of people wanting to believe it since it makes Warrior look whiny and egomaniacal. Why didn't Bruce Prichard ever tell this story? He hates the Warrior so he's certainly not going to go into his company-man act to protect him. Honky Tonk Man, a man who actually did force a power play on Vince over the title, has done a million interviews and I've never seen any indication that he's said anything besides Warrior always being the plan (or second plan, after Savage). You'd think Warrior himself would have said something about it at one point, while making sure to portray himself as the wronged party forcing the WWF to bow to him, but I don't think he ever has.
There's enough actual bad shit the Warrior said and did that I don't really care to make up other bad shit to go with it.
