Bret *Did* Agree To Lose ...
I'll probably get trashed for saying this, but I never had any sympathy for Bret Hart over the whole Montreal screw-job thing.
I actually think Vince was right.
Bret was leaving the organization and it's normally part of the wrestling tradition that the departing wrestler loses the title to the person who's staying. Bret should have agreed to lose to Shawn Michaels, in my view.
I watched "Wrestling With Shadows", the Brett Hart documentary, and that entire scenario was explained in detail. At the time, Hart had written into his contract that he had "reasonable creative control" over his storylines. Since Bret was playing the "Great Canadian Hero" thing at the time, he simply didn't want to lose the belt in Canada - it would just be unseemly. Or at least not at a PPV anyway ...
So he told Vince the Montreal PPV match could end in what they called a "schmaz", where Michaels' friends run in to interfere, Bret's friends run in to help, all hell breaks loose, and the ref double-disqualifies them. Vince *agreed* that the match would end that way to Bret's face. The next night, on Raw, was supposed to be Bret's last-ever appearance in the WWF before he went over to WCW. Even though it was being held in Ottawa Bret told Vince that on that Raw he would gladly "drop the belt in the middle of the ring to whoever you want any way you want, and you can replay it a million times for all the world to see". That's the best I can remember the quote, but it was very close to that.
In other words, Bret *did* agree to lose the belt, to whomever Vince wanted him to, whatever way Vince wanted him to lose, right in the middle of the ring, conclusively.
Just not in Montreal, but rather one day later on Raw. It was Vince who decided that Bret's idea just wasn't good enough, and hatched the scheme to have Bret "lose" in Montreal to Michaels. It's clear he did it simply to humiliate Hart. This is why Vince McMahon has been reviled by Canadian (and many other) wrestling fans ever since then - he proved himself, beyond a shadow of a doubt, to be a complete asshole.
So with all due respect to you, moviefan, Vince wasn't right. He was dead wrong.
