#1 Shinsuke Nakamura

A common theme on this list with four of the five wrestlers is they have come VERY close to their first world championship with the WWE, but have yet to win one. Shinsuke Nakamura falls into that category as well due to his failed attempts to take the WWE Championship off of Jinder Mahal.
Shinsuke Nakamura is my prediction to win the 2018 Royal Rumble, and as long as AJ Styles retains his WWE Championship against Jinder Mahal at Clash Of The Champions, we will have a dream match at WrestleMania that will definitely steal the show.
Cody Rhodes' uncle is a WWE Hall of Famer. More details HERE.
The WWE has rightfully turned Nakamura into a special attraction in the WWE, and I feel like we're in store for a tremendous moment to close the show when The Artist tosses that final competitor over the top rope.
