I was thinking of the recent NXT call ups, like Neville, Baron Corbin, Bo Dallas, The Ascension and Tyler Breeze and it seems that all have flopped or have hit a major slump. These are all guys that have been called up since 2014, when NXT became a Network selling point. My point being that maybe the over-saturation and quasi-brand that NXT has become has hurt NXT rather than help it. If you look at the call ups prior to the WWE Network's NXT series, like Seth Rollins, Dean Ambrose, Roman Reigns, Big E, The Wyatt Family and Xavier Woods, they were much more successful and were able to get their careers going. They had some slumps, but did not stay there. They were able to establish themselves and a clean slate, with no real ties to their NXT days so they can be molded and fitted into the WWE's main roster's style. What I'm saying is that WWE's decision to build a separate brand with NXT has allowed for over-saturation and has encumbered the WWE into booking them in a way to please their established fan bases, despite it not exactly working. In other words, the guys are too established to be considered call-ups because the WWE has an unassailable difference in style. Both in-terms of wrestling, storylines and booking. If NXT was smaller, and had less of an audience, they could establish characters that can be much more flexible to WWE's bookers and their style.
