#5 Shinsuke Nakamura
Shinsuke Nakamura's durability has proven itself. He remains amazingly over as 2017 concludes, despite a year that was notable only in how disappointing it was for him.
Arriving with much fanfare, Shinsuke Nakamura was quickly inserted in go-nowhere feuds with Dolph Ziggler and Baron Corbin. Following these, any remaining excitement was extinguished when Nakamura was sacrificed to Jinder Mahal's disastrous main event push.
Through it all, he proved that he can't always be relied on to put on good matches, his aura diminished. He was also often put in promos despite his being at times difficult to comprehend. Thankfully, these segments diminished as the year neared its end.
Shinsuke Nakamura and his fans must be casting hopeful eyes to 2018, believing that better things are on the horizon. If there were a Slammy for "Most Disappointing Superstar," Shinsuke Nakamura would take it.
