That Aew spanking and them 700,000 ratings got Vince piss
Maybe I over estimate VKM's pettiness but I think this is a major part of it. They're "minor league" in his eyes and the Wednesday Night Wars only reaffirmed this.
Is there one NXT star in the last 5 years he has really gotten behind?
Drew, but he was once his golden boy already so not quite the same. Perhaps KO, but that took forever. It seemed like Finn at one point but then we got all that "he's not over enough" talk. The list of guys who were huge deals in NXT only to be mismanaged on the main roster, however, is endless.
When I think of the big pushes in the last few years of "new" guys, a lot of them are guys (Bobby, Braun) who bypassed NXT all together
