The Wrestling Observer Newsletter notes that the idea behind NXT has changed a lot lately as Triple H loves all the praise he gets for NXT on social media. WWE originally was looking to train new talents from the bottom to the main roster but it appears they are recruiting top talents for the NXT brand itself. The idea is to replace some of the top indie stars who can already work good matches with more indie stars.

In short: We're going to keep a steady crop of independent talent in NXT to handle the grunt work of the brand part of NXT along with our self trained talent that are ready instead of putting green as gooseshit rookies in front of cameras when they aren't ready.
