#1 Kevin Owens

Kevin Owens has done almost everything he needed to complete the WWE Grand Slam, except for find a tag team partner. For some reason, he and Sami Zayn never competed for the Tag Team Championship, leaving those titles the only one left for KO to win in the WWE. The former NXT Champion has had an excellent run on the main roster, beating John Cena clean in his first match. He won the Intercontinental Championship quickly afterward, going on an effective reign before trading it with Dean Ambrose through the transition between 2015 and 2016.
Owens moved to bigger and better things soon after, winning the Universal Championship on RAW and the United States Championship later, at WrestleMania 33. However, since losing the star-spangled prize after trading it with Chris Jericho and AJ Styles, the Prizefighter has not picked up another championship. It has been too long for somebody that has the ridiculous talent and charisma that Owens possesses. Hopefully, he finds somebody who can trust him as his tag team partner and wins the tag titles, fulfilling his prophecy, before inevitably stabbing that person in the back as he has been known to do.
Or have the times changed?
