Winning the WWE Championship from CM Punk and The Rock would deliver a lot of heat for John Cena. But he could've taken it to another level in 2014. Ending The Undertaker's WrestleMania streak would have cemented Cena as the biggest heel possibly in WWE history.

The Undertaker's steak ended at WrestleMania 30 against Brock Lesnar, who instantly became the biggest star in WWE. In this scenario, Lesnar could be loosely associated with John Cena's faction through Paul Heyman.

Anyway, defeating The Undertaker at WrestleMania with some major help from his faction would mean Cena would do the unthinkable.

Since it would not be a clean finish, John Cena would get more heat. This would have been the peak of his run as a heel.
