#4 United States Title
It's hard to imagine The United States title staying with Shinsuke Nakamura, especially with Rusev now in the hunt for the title. The best place to make the switch probably lies at The TLC pay per view. In fact, it could be a launching point for Rusev after several months of being stifled and might even lead to something better on down the line.
As for Nakamura, he has been largely non-existent as United States Champion. Making a title change at TLC almost needed in order to maintain the prestige of the title. Beyond that, Rusev has such a die-hard fan base, which is only going to make the decision that much more popular to put the title on him.
In the end, Nakamura's time as United States champion has done nothing for WWE, anyone he has fought or even himself. Furthermore, the title hasn't had a lot of television time in a while and WWE hasn't done anything meaningful with the title when it was on television. If nothing else, its time for a change and it starts on Rusev day!
