#3 Kevin Owens
Kevin Owens was the longest reigning Universal Champion until Brock Lesnar overtook his reign as the champion. Owens won the championship after Finn Balor vacated it a day after winning it at 2016 SummerSlam.
Owens lost it to Goldberg at WWE Fastlane before the WWE Hall of Famer dropped it to Lesnar at WrestleMania 33. Since then, Owens didn't get his rematch clause as he was drafted to Smackdown Live where he won the US championship and was drafted back to Raw where he is currently feuding with Braun Strowman.
Before Reigns take on Lesnar, Owens will go one-on-one against Braun and the winner will win the Money In The Bank briefcase. It won't be a bad booking if Owens wins it and goes on to become a champion as he is too good to be away from the main event scene.
