#4 Dolph Ziggler

Another long shot scenario, this one would probably only work if WWE were able to take the title off of The Showoff leading up to WrestleMania 34. Having Ziggler walk out of Fastlane would be great for a shock factor and could leave an air of unpredictably along the way, but only if WWE somehow gets back to the dream match between Nakamura and Styles.
What also hints at the Dolph Ziggler scenario is his newly signed contract with the company, which could result in him getting one more run with The WWE title to make him happy. Of course, that run should be short-lived and eventually move back to the dream match, but it would still be a great swerve to see none the less.
