Flagg scored 31 points and Harper poured in 16 as Harper's San Antonio Spurs claimed a 76-69 victory over Flagg's Dallas Mavericks in an NBA Summer League showdown in Las Vegas. Despite his team being on the losing end, Flagg put on a clinic.

Cooper Flagg's summer league debut wasn't perfect. But there were flashes of greatness, and at this stage the Mavericks would be wise to let him fail.
