#3 Triple H tried to keep Keith Lee in NXT
Triple H has done an incredible job with the NXT brand. The likes of Keith Lee, Seth Rollins and Big E have thrived under the black and gold brand. NXT was meant to be a stepping stone to get to the main roster. Either Smackdown or Raw, but that hasn't been the case in recent years.
Superstars have opted to remain on the NXT brand for a multitude of reasons. Also, given how some superstars have been used on the roster. You can understand why, but at the end of the day,NXT is still a developmental brand. Keith Lee was always going to make the move up. Although he would've preferred to stay a bit longer. Even Triple H had tried his best to keep him at NXT longer.
Unfortunately that was not possible and when Lee made his debut, it was an impressive one. Defeating Randy Orton in the middle of the ring isn't a bad start. Behind the scenes, rumors of Vince McMahon's creative struggles with Lee began surfacing. This led to multiple changes to Keith Lee's character. WWE released Lee in November 2021 a few weeks after being drafted to Smackdown. It's clear Lee's move up didn't exactly work out for the best.
