4. A Mystery Hit And Run
https://www.youtube.com/watch?v=GybWQWb9JzM One of the most memorable angles WWE ever did in the Attitude Era was Stone Cold Steve Austin being the victim of a hit and run. A reboot would work well for Cena. He'd compete at Hell In A Cell, then be pictured leaving the arena. As he made his way through the car park, out of nowhere, a car would speed over and take him out. He'd be out injured, while WWE ran a "whodunnit?" story in his absence. When he finally returned in December, he'd reveal that he saw the face of the assailant. This big announcement would then lead to a WrestleMania match.
