Cooper Flagg may not have been happy with his professional debut in the NBA Summer League, but he still drew some rave reviews afterward.

Flagg's first points as a pro came on a slam dunk with less than five minutes to go in the first quarter. The Mavericks guard finished with 10 points, six rebounds and eight assists in his debut. He played 32 minutes, making 5 of 21 field goals, missing all five of his three-point attempts.
