10. Kevin Owens
There's been a lot of speculation that WWE might be building toward a unification of the Intercontinental and United States Championships, and regardless of whether or not that's on the cards, pitting Alberto Del Rio against Kevin Owens has all the makings of a great rivalry. The prospect of Owens and Zeb Colter exchanging barbs during promos is obviously something well worth getting excited over, but it's what the former NXT Champion and Del Rio would do together in the ring which is the most thrilling prospect. After all, since reaching the main roster, Owens has proved that he can get a great match out of just about everyone, and he would no doubt have incredible chemistry with Del Rio. The most enticing prospect about this one is the fact that it would be something new. Despite the fact that the WWE has an extremely deep roster right now, it often feels like they produce the same matches again and again on a weekly basis, so Owens and Del Rio squaring off would not only be fresh and original, but a guaranteed technical classic when they meet in the ring regardless of whether one or both titles are on the line.
