#1 Maybe Vince McMahon wants him to develop a more unique kind of character
One of the primary reasons why Vince McMahon has been able to create an empire that has transcended geographical boundaries and lasted for so many decades is because of his ability to tell stories and create compelling characters that endure over time.
Keith Lee, for all his accomplishments, is still little more than a skillful competitor, at least in the WWE main roster. Vince McMahon may want him to spend time in the WWE Performance Center to develop a character that endures the test of time, like Stone Cold Steve Austin or The Rock.
Just compare how much cooler Roman Reigns is, in his current avatar, as opposed to the man he was when he was just your standard, everyday babyface, and Vince McMahon probably realizes this about Keith Lee.
