#3 Introduce a new number one contender for The United States title
Shinsuke Nakamura took a huge loss to Seth Rollins at Survivor Series and while it was a very entertaining dream match between the two, Nakamura still needs some kind of momentum moving forward. He also hasn't had a solid feud or opponent for quite a while now, which is another reason why WWE needs to get something going.
With that being said and WWE seemingly teasing a match between Shinsuke Nakamura and Randy Orton earlier this year, maybe the company should have the two butt heads over the US Title. In fact, not only would it help Nakamura gain some of his momentum back, it also puts two very entertaining storytellers in the ring together.
Think about it! Rollins versus Nakamura was already a thriller from beginning to end and WWE could probably do the same with Orton and Nakamura as well. In the end, its up to the company on what they want to do here, but The RKO versus The Kinshasa would be a very interesting feud to watch.
