#3 Kevin Owens
Right now, Kevin Owens is out of action with an ankle injury. It isn't certain how long he will be out for and when he will return to WWE, with the current situation. If KO does come back in the near future, he has to be in line for a big push. It would be smart to build on the momentum he earned by defeating Seth Rollins at WrestleMania.
After that massive victory, Owens should return to the main event scene of Monday Night RAW. He is good enough to hold the WWE Championship. The former Universal Champion has been one of the best babyfaces in WWE over the past year. He is great at everything, from wrestling to promos.
Kevin Owens would be a phenomenal choice to go on a long WWE title program with Drew McIntyre. Him winning wouldn't even upset the WWE fans, as they are very much behind him. A lengthy United States Championship reign would be a more realistic possibility for Owens right now.
However, if he is allowed to showcase his tremendous in-ring ability, it would surely propel him to the top of the card. It is baffling how a Superstar so talented is not a permanent main-eventer in WWE. Right now, they have the opportunity to right that wrong.
