NXT Call-Ups

The biggest surprises might come from the wrestlers from NXT that debut.
Someone like EC3 might make a quick jump to the main roster after a brief run in NXT. Bobby Roode and Drew McIntyre both did it so EC3 might have signed a similar type of deal.
The NXT Title scene is currently filled with the likes of Tomasso Ciampa, Johnny Gargano and Aleister Black, so if EC3 were to remain in NXT with hopes of a title shot, he'd likely have to wait a little longer.
And speaking of Black, he gets his rematch for the title at NXT: Phoenix. Since he already lost the belt, he'll probably fail in his bid to reclaim it.
He's clearly done most of what he could do in NXT so him debuting the next night in the Rumble might be the next logical step for Black.
And then there's the uber-talented Velveteen Dream.
He's stolen the show on almost every Takeover Special he's been on albeit without any gold to show for his troubles.
The crowd loves him and he was clearly the most talented member of the last version of Tough Enough.
The crowd would go nuts if he did debut and he even danced around the subject when asked by Cathy Kelley regarding what was next for him in NXT.
Hopefully, he'll be able to maintain a lot of his character's traits on the main roster when/if he debuts.
