The Dallas Mavericks came up short against the San Antonio Spurs on Saturday, falling 76–69 in their second NBA Summer League game. But despite the loss, Cooper Flagg was undeniably the best player on the court.

After a quiet debut against the Los Angeles Lakers on Thursday—where he finished with just 10 points on 5-for-21 shooting and later called it “one of the worst games of my life”—the No. 1 overall pick bounced back in a major way.

Flagg led all scorers with 31 points in 31 minutes, adding four rebounds while shooting 10-for-21 from the field and 3-for-9 from beyond the arc.

On Sunday, following his standout performance, the Mavericks shared a notable stat: Flagg’s 31-point outing marked the most points scored by a No. 1 overall pick in Summer League since 2017—an impressive feat that adds another milestone to his young career.

Dallas also announced on Sunday that they plan to shut down Cooper Flagg for the remainder of Summer League play—a move that comes as no surprise given how much he’s already shown in just two games.

Flagg, who is still just 18 years old, continues to show his rare ability to impact the game in every facet. Offensively, he can play both on and off the ball, has experience running the point, and can score at all three levels. Defensively, he’s capable of guarding virtually every position on the floor—and doing it well. It’s that versatility and all-around game that made him the projected No. 1 pick for nearly his entire freshman season at Duke.

Dallas is set to return to action Monday night in what could've been a highly anticipated matchup against the Charlotte Hornets, who drafted Flagg's Duke roommate and teammate Kon Knueppel.
