Cooper Flagg’s Summer League run is officially over, as the Dallas Mavericks have decided to shut down the No. 1 overall pick after just two games. The move, according to team sources, is focused on managing Flagg’s workload and ensuring his long-term health as he prepares for his rookie season.
While brief, Flagg’s Summer League stint gave fans and analysts a strong glimpse of what he could bring to the Mavericks both now and in the future. After a rocky debut against the Lakers, where he scored 10 points on 5-for-21 shooting, the 6-foot-8 forward responded in a big way in his second game against the San Antonio Spurs. Flagg erupted for 31 points, four rebounds, and a block while showing more confidence and control as the Mavericks tested him in a point-forward role.
“I think I’ve been solid. I’m exhausted,” Flagg said after the game, summing up the physical and mental challenge of being a lead playmaker on the floor.
The Mavericks have made it clear they’re investing in Flagg’s development beyond just his scoring. Head coach Jason Kidd gave him significant offensive responsibilities, including initiating plays and managing tempo—tasks that usually aren’t handed to rookies in their first NBA action. That trial by fire, though exhausting, allowed Flagg to grow quickly and display his toughness.
Still, some may wonder: Will the Mavericks regret pulling the plug so soon? With only two games of real-time experience as a lead ball handler, it’s fair to question whether missing out on more Summer League reps could slow Flagg’s adjustment to the Mavericks’ system. These minutes—especially in a low-pressure environment—are valuable for building chemistry, sharpening instincts, and getting comfortable in an NBA structure. If anything, it puts more pressure on training camp and preseason to pick up where he left off.
By shutting him down now, Dallas avoids unnecessary risk while still walking away encouraged by what Flagg showed. The flashes of scoring, defense, and leadership all suggest the Mavericks have a foundational piece in place.
The decision may shorten his Vegas run, but it doesn’t change the fact that Cooper Flagg passed his first NBA test. With his work ethic, versatility, and early maturity on full display, the Mavericks can feel confident they’ve landed a future star—and they’re already thinking long-term.
