#1.) Brock Lesnar fails the MITB cash-in
WWE has really made sure to drag out the MITB cash in as much as they possibly can. From Seth Rollins constantly getting the better of Lesnar, it does seem as though WWE is eventually going to pull the trigger and make Lesnar Universal Champion for the third time. But what if WWE decided to pull off a swerve and have Lesnar legitimately fail the cash-in?
It would be unexpected and chaotic but amazing at the same time. However, it would also mean three consecutive failed cash-ins for men, something that seems unlikely.
