Braun Strowman

Braun Strowman wasted his Money in the Bank contract.
There is no other way to put it.

At first, he had the right idea.
He intended to cash it in at the end of Universal Championship matches. This was a sound strategy; in addition to being a hulking monster, Braun would be fresh, whereas his opponent would be exhausted after a gruelling match. This all but guaranteed Braun the Universal Championship.
Then, he took leave of his senses.
First, he handed his Money in the Bank contract to Baron Corbin, despite knowing that he was going to double-cross Roman Reigns later in the night, by betraying him during their tag-team match against Dolph Ziggler and Drew McIntyre. He knew that he was going to beat down Roman, but didn't think to cash in after.
Then, the next week, he didn't cash in despite the fact that every heel in the locker-room had beaten the Shield to a pulp.
Let this sink in.
He wanted to cash in at the end of championship matches but didn't on two separate occasions when the champion was lying unconscious in front of him.
He finally cashed in inside Hell in a Cell, because he actually believed that the structure would prevent outside interference, despite the fact that every WWE structure designed to prevent outside interference inevitably has outside interference take place.
And would you believe it, Brock Lesnar interfered, costing Braun Strowman his Money in the Bank briefcase.
I can't even.
