#3 Braun Strowman
Braun Strowman has been one of the most protected characters in recent WWE history. He has been a monster that is unstoppable and wonderfully entertaining. This strong booking and support from the management is the one and only reason why I would keep Strowman so high on the list.
Much like Samoa Joe, Strowman's character doesn't match with the concept of a Money in the Bank winner, neither does Strowman's. Strowman won the Tag Team belts alone (Do you really want to count Nicholas?). He didn't need a partner to beat two champions alone, so why would Strowman want to win something which makes becoming a champion infinitely easy for him?
If he has rejected easy challenges, then how would his character match with the demands from a Mr. Money in the Bank? This reason halts him from being an out-and-out favourite, but considering how WWE loves deviating plots according to convenience, it wouldn't be surprising at all for Strowman to win the briefcase.
Chances: High
