#2 – Shinsuke Nakamura
Let's be honest here, Shinsuke Nakamura's time in the main roster is over. He's done what he had to do and there is nothing left for him really. Unless he really wants to get his hands on the tag-titles, he should think about a move back to NXT.
The move will not only help him compete for the gold again but also help the others in NXT. Nakamura has so much experience that he can guide the ones in NXT and help them get ready for the main roster.
His WWE contract does expire in 2019 and there are no real indications that he will be handed a new deal. So, on his way out, the former NJPW star should help put someone over in NXT and leave as there is no one on the main roster that can be put over by him.
