#1 Shinsuke Nakamura
This has WrestleMania 36 written all over it! Daniel Bryan was given the opportunity to join Shinsuke Nakamura last year when Sami Zayn asked him to join them, on SmackDown Live. Bryan was teasing bringing back the Yes Movement back then, and now that he has fully brought it back, that feud which was teased last year could come full circle.
Nakamura and Bryan have not had a feud on WWE television since Bryan's return from injury, and this is a dream match that most fans want to see. We could perhaps see this feud extend till later this year at WrestleMania 36, which will happen in April, where the two exceptionally talented wrestlers could go at it, to culminate the rivalry.
With Bryan now a babyface and Nakamura continuing to be a fantastic heel, with the assistance of Zayn, this is one feud that could grab all the headlines on the Blue brand. Neither Superstar needs to hold a title to make this feud work on SmackDown.
