#1: Roman Reigns vs Brock Lesnar, WrestleMania 31

The most shocking thing about this whole scenario is that the person who won the match wasn’t supposed to be in it.
This earns the number one spot in the list. Seth Rollins cashed in his Money in the Bank briefcase at WrestleMania 31. This was special for a number of different reasons. Not only is Seth the first and only person to cash in at WrestleMania, but he is the only person to cash in during the middle of a match.
Look who just shut down all of Tony Khan's critics! More HERE.
Seth’s music hit during the middle of the match. No one in that arena or watching at home wanted to see Roman beat the Beast, and take the title. This was such a surprising turn of events. We all thought that Roman was going to win the title, but that didn't happen.
Most Money in the Bank winners has cashed in their contract after a match. This trend was started by the ultimate opportunist, Edge. Edge cashed in at New Years Revolution in 2006. This was after John Cena had just faced five other superstars in a gruelling Elimination Chamber match. This would soon start a trend as wrestlers would pick their moment when the world champions were at their weakest.
Though Seth didn’t wait until the match was over, he came down to the ring in the middle of the match. After both Roman and Lesnar had beaten the hell out of each other, and Brock had just hit a vicious F-5 on his opponent, Seth Rollins charged the ring. Going for a curb stomp on Lesnar, but Brock picked Rollins up in the air for an F-5 position. As Brock turned around, Reigns hit a massive spear on Brock, dropping Seth. Rollins scurried to his feet and landed a curb stomp on Reigns, pinning him to win his first WWE Championship.
