#1 Shinsuke Nakamura

When Shinsuke Nakamura signed with WWE everyone expected that he will create 5-star matches and will constantly be in the main event picture but sadly that was not the case at all.
In the beginning, it looked like that WWE will make Shinsuke a superstar. He was booked pretty strongly in the beginning, he even won the 2018 men's Royal Rumble match and went on to face AJ Styles in a dream match for the WWE Championship at WrestleMania 34.
He turned heel at WrestleMania and continued the rivalry with Styles, but after that rivalry, WWE had no direction for Nakamura. During the second half of 2018, he was not booked properly, though he became the US Champion he couldn't make a statement as the US Champion.
Since then we have seen Nakamura only a few times on TV. His last televised match was against Kofi Kingston a month ago.
One way that WWE could bring Nakamura back and rebuild him is by making him the 24/7 champion. There is a lot of buzz around the 24/7 championship but the championship itself is not taken seriously by the fans.
WWE could use the star power of Nakamura to make the championship look a little prestigious and a run as the 24/7 champion will also help Nakamura to gain back his credibility.
