Sooner Nation, the Joe C. era is officially winding down after his surprise retirement news. The big question: who’s ready to fill those legendary shoes as OU’s next AD? Early buzz has Zac Selmon (Mississippi State) as the frontrunner—he’s a Castiglione protégé with a hot track record. But don’t count out Wren Baker (WVU), Kirby Hocutt (Texas Tech), or even in-house riser Marcus Bowman. With the SEC move looming, this hire could define the next decade. Who’s your pick to lead the Crimson and Cream? #Sports #Sooners #Oklahoma
