1) Dolph Ziggler

Dolph Ziggler has achieved all he is ever going to in the WWE. While he is a two time World Heavyweight Champion, his days of being a serious title contender are way behind him.
He is now, a glorified jobber to the stars and is currently doing a whole load of nothing on Tuesday nights. With the US title scene being dominated by the likes of AJ Styles and Kevin Owens too, Ziggler needs a change.
Moving to Ziggler to NXT would be the best move for all involved. He would no doubt put on some great matches with the likes of Drew Mcyntire, Bobby Roode and Aliaster Black and a victory over Ziggler would also help elevate those guys further before their ascension to the main roster.
