Is that contract MJF has a money in the bank style one or just a match contract?
It's like MITB. Christian Cage "cashed" his in during the final stretch of the Cope/Mox Main Event at this year's Revolution for example.
I get the feeling we gonna see some fuckery about that soon though... since they have to sign it, I'm sure they'll do something like someone else showing up, disrupting the situation and putting their name on it instead at some point. Probably not this time, but maybe next year or so.
Depending on what their long time plan is here, I can also see them pulling of something like MJF intentionally losing via DQ to Hangman, after he gets frustrated by the fact he can't put him down for the count, just to sign the contract afterwards to capitalize from that... I think that would suit his gimmick.
I doubt they will do that, but them running the same "Heel doesn't want/will not sign the contract, but wants (and gets) a title match anyways" with both those contracts at the same time is just meh... especially if they don't end up doing something more special with either of them.
