Randall Stephenson has nothing to do with basketball except as chairman of the athletic director search committee. He is the CEO of football.
Not sure if he cares about hoops.
The name I've seen connected to the athletic director position is Rick Hart, formerly of SMU. Not sure if he's the guy, but I've seen his name floated. Former associate AD at OU. He was AD when the BMDs at SMU funded the renovation of Moody Coliseum. SMU was in a different place, as they were trying to get into a power conference. They eventually got from the American to the ACC after flirting with the old Pac-12.
