1. The Champ Is Here
Those "we want Cena!" chants at TLC could well have opened up a huge can of worms - especially considering the impending return of Big Match John. As unpopular as it may be among certain sections of the audience, a Cena vs. Reigns feud would be monumental in scale - similar, in many ways, to Hogan vs. Warrior some 25 years ago. Pairing the company's two biggest babyfaces against one another would certainly cause a stir, if only just to see who would win. It's not really a match for the Royal Rumble - perhaps WrestleMania 32, or even an event further in the future - but now that Roman is champion, seeds must definitely be sown. The eventual showdown would be looked back upon as a defining, torch-passing moment in Regins' career, so it would be majorly important for WWE to ensure an appropriate crowd reaction. Simply putting on a great match would be one way of doing it, sure - but how about a Roman heel turn...?
