Bo Aldridge led the team with 22 points, while Mohamed Diakite and Alonzo Dodd contributed 15 points each. The Sooners, who were 28.5-point favorites, struggled with 15 turnovers and 15 missed free throws. Coach Porter Moser apologized to the fanbase and acknowledged that the team's performance was not good enough.
