All of this could play brilliantly into a John Cena heel turn. The star recently said he'd be up for the turn in the right circumstances and admitted that he even bought new gear for a proposed turn in 2011. The story is logical. Cena feels threatened by Reigns' younger force, so he ends up turning heel in the run up or even at WrestleMania 32. WWE could even book heel Cena as the winner via a chair shot or something. The story then would be Reigns' quest for the title and revenge at WrestleMania 33. But in honesty, Cena is going to be heel in a Reigns feud whether he's presented as one or not. In that respect, it might be just as well to keep him face. Ironically, he might end up being cheered if he was formally sent heel.
