#1 - Shinsuke Nakamura (WWE SmackDown)
Shinsuke Nakamura has become the most talked-about wrestler on the WWE SmackDown roster in the last two weeks. WWE has taken a complete U-Turn with Nakamura and has made him a favorite to win the Rumble.
It all started during a Gauntlet match two weeks ago on SmackDown where Nakamura defeated three of the biggest names on the SmackDown roster back to back; Rey Mysterio, King Corbin, and Daniel Bryan.
Nakamura ended up losing the match because of Roman Reigns, sowing the seeds for a potential match-up down the line. Shinsuke turned face in the process and defeated Jey Uso the next week on SmackDown, promptly starting a feud with Roman Reigns' group.
Nakamura is yet to win a top championship in WWE. However, the King of Strong Style might be getting an opportunity to change that. Nakamura has already won a Royal Rumble before, which makes him big enough of a threat already to the rest of the match participants.
Nakamura's performance in the last two weeks has made him the last-minute favorite to win the Royal Rumble. With a feud already begun between the Artist and the Head of the Table, winning the Royal Rumble would make the match official for WrestleMania 37.
