#6. King Corbin

King Corbin hasn't had a great run these past few months. Late 2019 on SmackDown saw him have a seemingly endless feud with Roman Reigns, who eventually beat him at the Royal Rumble and later at Super ShowDown in a steel cage match.
This WrestleMania, Corbin faced Elias in a match that seemed more appropriate for an episode of RAW or SmackDown than it did for WrestleMania. Elias ended up beating Corbin via a roll-up and just like that, any momentum that the former United States Champion had is gone.

It always seems as though Corbin is a step away from a breakthrough, but in the eyes of many fans, he isn't on the level that WWE wants him to be. He won the Money in the Bank briefcase in 2017 but lost his cash-in against Jinder Mahal. He's far from ready this year, but we wouldn't be surprised to see him in the men's ladder match. However, Corbin shouldn't be winning the briefcase anytime soon.
