8 Current WWE Stars Just One Title Win Away From Becoming Grand Slam Champion
3. Kevin Owens - Tag Team Championships
Kevin Owens is the only Superstar on this list, who needs to win the Tag Team Championship to join the club of Grand Slam Champions. The Canadian wrestler won the Intercontinental Championship at Night of Champions 2015 with a victory over Ryback.
After he impressed the backstage officials with his work as the Intercontinental titleholder, they booked him to seize his maiden Universal Championship on a RAW episode, where he defeated Roman Reigns, Seth Rollins and Big Cass in a fatal four-way elimination match. In 2017, he moved to SmackDown Live and became the United States Champion with a win against Chris Jericho.
Given that 'The Prizefighter' has often betrayed his friends, it is likely that WWE may have kept him away from the tag team gold on purpose. However, since he has turned face now, there is a possibility that the creative team would insert him in the tag team title picture eventually.
