6: A Member of the New Day 5/10
This one does largely depend on which member of The New Day is added to the match. If, as most people seem to think, it is Big E, then their chances increase slightly but, given the nature of The New Day's gimmick, it seems unlikely any of them will be competing for a top prize anytime soon.
Big E was initially the bookies' second favorite to win the match, and there have been plenty of rumors that he is in-line for a push over the Summer.
While Big E is potentially a huge star for the company, now does not seem like the right time to pull the trigger and give him the briefcase, as amusing as that would be.
