I was thinking myself yesterday that they need a good shuffle up in NXT because the roster feels like it's become a bit stale. They're probably in a very sticky situation though because of Mania season coming up and then the debut on the new channel next year.
Bron, Melo & Ilja need to be gone. Dijak feels like he's hit his ceiling, I don't really know if Corbin is really doing too much either.
