I know this idea is really out there but What if WWE decided to add a third person in the WWE title match at mania?
I know it’s a far fetch idea but with the fact that it was already reported that WWE made a mistake with the contract they use for the contract signing segment. How about you use that to there advantage. You have Kofi and Bryan enter the ring and just before the introduction, you have vince mcmahon come out and say that Kofi should have read the contract he sign before signing it and that the contract he sign wasn’t for a title match at mania but for a match at fastlane. So since the contract is no longer valid he decided that while kofi will still get his title shot, it will be a triple threat match instead and that the third participant is Kevin Owens.
After that you either go with Kofi beating Owens for the belt or owens pinning bryan or kofi for the belt.
