#4: Reincarnation of Dolph Ziggler
Dolph Ziggler took part in a WWE Championship match last December, but his stock has fallen miserably ever since then. He was stuck in a feud with Crews and Kalisto at the beginning of 2017 which did not do any good for anyone. Ziggler has been used as a glorified enhancement talent for the NXT call-ups throughout the year.
He was surprisingly put into the US Championship match at Clash of Champions, and many believe this decision has been made so that Corbin or Roode don't take the pin during the match. However, Ziggler has made it clear that he isn't happy with his current status in WWE and that could lead WWE to put the title on him for a short run in the mid-card.
Ziggler is one of the best in-ring workers in the company but has been stuck with a stale gimmick now for a while. His heel run has been massively disappointing, but a title run can make him relevant again, hopefully.
