#2 Storyline that should end at Elimination Chamber - Roman Reigns vs. Kevin Owens
Kevin Owens will get another opportunity to face Roman Reigns if he can win SmackDown's Elimination Chamber match. While Owens' work on the mic and in matches with Reigns has been top-notch, this feud needs to end.
WWE usually sets the limit of an ongoing feud to three PPV matches. When it extends past that stage, it seems like there aren't any fresh ideas to stem the tide.
The former Universal Champion had a legitimate gripe in the first two matches as Jey Uso played heavily into the finishes of both contests. They had a huge third match at the Royal Rumble where Reigns beat the Prizefighter for the third time in a row.
While a challenger will win SmackDown's Elimination Chamber match to face Reigns at the PPV, Owens has had his shots at the Universal Championship. He's one of the best performers in WWE, but someone else should get the next few shots at the Tribal Chief.
There is also the possibility that Reigns could defend his title several times before WrestleMania. Those potential title shots - and the one at Elimination Chamber - should be saved for someone other than Owens. The Tribal Chief's heel reign as Universal Champion is also probably why WWE needed to change both Cesaro and Shinsuke Nakamura to babyface characters on SmackDown.
