They hired Mike Mansury last year. He's the guy who was producing NXT black & gold at it's peak. The WWE told him they were going to hand him the production reigns whenever Kevin Dunn retired, but the beaver refused to step down so he bounced. He worked on Pat McAfee's show, then moved to some MMA organization in Asia until Tony convinced him to move back to the USA for AEW.
Vince McMahon mustaches are not a gimmick.
