#2 Dolph Ziggler

The more I think about this one the more sense it makes. Dolph Ziggler could win the 2018 Royal Rumble match and add it to his long list of accomplishments.
Lots of people say that Ziggler will return and challenge the new U.S Champion, but would this really make sense? Why would Ziggler come back to fight for a title that he dumped in the ring? He clearly doesn't care about it and it would be very strange if all of a sudden he wanted it back.

What if Ziggler entered the Rumble match and won? It would prove that the WWE Universe was wrong in doubting him. He will be able to re-establish himself as a main eventer.
