#4 Avoids Roman Reigns taking a loss

Roman Reigns is one of the biggest things in WWE right now and while one would assume that a feud with The Fiend would be on the horizon, why does it have to be? Furthermore, wouldn't putting WWE's two biggest personalities on a collision course eventually force them to make a very difficult decision?
In all honesty, that seems like a situation that WWE can't afford to put themselves in, which is why the idea of John Cena versus The Fiend becomes much more appealing. Not only does that create a situation where the company isn't forced to make a decision between The Fiend or Roman Reigns, it also helps Reigns not have to take a crucial loss.
With that being said and Reigns versus The Fiend creating obvious problems, Cena versus The Fiend would be a much easier decision. It would also give Reigns a chance to have a dream match of his own with Goldberg or someone else, which could be very lucrative for his championship chances moving forward.
