#2 Aleister Black
Aleister Black has started his career on the main roster like a house on fire and has incredible momentum behind him. His tag-team with Ricochet is one of the most exciting duos in WWE right now and it's clear Vince McMahon and WWE management see him as a star.
Black has the ability inside the ring, the promo skills as well as a unique character. He has everything needed to excel where former NXT Champions have faltered.
#1 Roman Reigns
With Roman Reigns returning to full fitness from his health scare, don't be surprised if he gets a huge push in the coming months. He could even be one of the top stars moved to SmackDown as one of the faces of the show on FOX.
Reigns is rightly considered a top star by WWE and Vince McMahon will put him back in world title contention sooner rather than later.
