#3 Shinsuke Nakamura somehow helps Cesaro win at WrestleMania 37
Just as Murphy has been an ally to Rollins during this WrestleMania 37 angle, Nakamura has stood by the side of his friend and tag team partner. It's added new dimensions to SmackDown while also allowing both men to be fan favorites.
Cesaro has always received cheers from large portions of the WWE Universe, but his booking hasn't always met those cheers. WrestleMania 37 seems like the perfect spot to remedy that. The Swiss Superman is on a great run after big wins over Daniel Bryan and a good showing at Elimination Chamber.
Rollins and Nakamura even faced off at Fastlane after the Messiah hurt Cesaro the previous week. Once Rollins had prevailed over the King of Strong Style, Cesaro returned to protect his friend.
Like Murphy, Nakamura is a part of the Andre the Giant Battle Royal on the WrestleMania 37 go-home episode of SmackDown. Either man could feasibly win the match. At the very least, the two could come to blows during the contest due to their allegiances to Rollins and Cesaro.
Due to both men being involved, it seems like there should have at least been some sort of tag team match featuring all four men. It would have added another layer to the storyline and could have given Murphy and Nakamura more air time on SmackDown.
While the heels trying to cheat to win is more likely, Nakamura could very well show up. The chances of him showing up increase even more so if Murphy comes out first to interfere in the WrestleMania 37 match.
However, making the match at WrestleMania 37 a tag team match would have robbed Cesaro of the chance to have his first featured singles match at the PPV. For that reason, showing up to help his friend at WrestleMania 37 could be a way for Nakamura to get a brief WrestleMania moment this year.
Nakamura's booking has been inconsistent during his WWE career but he's always performed when given a chance.
