Cooper Flagg Debuts in NBA Summer League, Secures Narrow Victory

In a much-anticipated debut, Cooper Flagg, the Dallas Mavericks' first overall pick in the 2025 NBA Draft, played his inaugural game during the NBA 2K26 Summer League on July 10, 2025. The Mavericks triumphed over the Los Angeles Lakers with a close score of 87-85, despite Flagg's inconsistent performance on the court at the Thomas and Mack Center in Las Vegas.

Flagg's statistics from the game featured 10 points on 5-for-21 shooting, including an uncharacteristic 0-for-5 from beyond the arc. Additionally, he contributed 6 rebounds, 4 assists, 3 steals, and 1 block, showcasing flashes of the talent that led to his selection as the top pick. A pivotal moment occurred late in the game when Flagg executed a crucial block against DJ Steward, which helped secure the Mavericks' victory.

"I couldn't really get into a rhythm; it's a different environment, obviously very different from college, and it's probably very different from what the real NBA is gonna be like," Flagg remarked post-game. This sentiment underscores the challenges faced by rookie players transitioning from college basketball to the professional level.

The atmosphere at the arena was electric, filled with enthusiastic fans supporting both Flagg and his opponent, Bronny James, the son of basketball legend LeBron James. The crowd reacted warmly when Flagg was announced as a starter, showcasing the excitement around his professional debut.

Mavericks head coach Jason Kidd expressed optimism regarding Flagg's performance, stating, "We're all excited. I've seen enough of him on tape, so now it's good to see him on the floor." Kidd emphasized the importance of effort and grit over perfection during the summer league, a platform for teams to assess their rosters and find emerging talents.

Historically, the NBA Summer League has provided a stage for rising stars to showcase their skills. This event not only allows players to gain invaluable experience but also serves as a fan engagement opportunity. Flagg, who received considerable attention during his college career at Duke University, has already garnered a significant following. Young fans like 15-year-old Baer Epple, who traveled from Seattle, expressed enthusiasm for Flagg’s potential. "Even more of a fan now that they got Cooper Flagg," Epple stated.

Despite the initial jitters and a challenging shooting night, Flagg's performance left room for optimism among fans and analysts alike. His ability to impact the game beyond scoring, coupled with his willingness to adapt, signals potential growth as he continues in the league.

Looking ahead, Flagg's journey in the NBA will be closely watched as he endeavors to refine his skills and establish himself as a key player for the Mavericks. With a foundation built on hard work and the ability to respond to adversity, Flagg is positioned to make a significant impact in the coming season, as he continues to navigate the transition from college to the professional arena.
