Head coach Jason Kidd, speaking during Flagg’s much-anticipated Summer League debut, emphasized that the 18-year-old forward will be entrusted with significant responsibilities from day one.

“When you have someone like Cooper who can handle, who can shoot, who can pass, you want the ball in his hands,” Kidd explained, highlighting Flagg’s maturity and poise well beyond his years.

Flagg’s debut against the Los Angeles Lakers in Las Vegas was a microcosm of his promise and the learning curve ahead. He logged 10 points, six rebounds, four assists, three steals, and a block in 26 minutes, helping Dallas edge out an 87-85 win.

While his shooting (5-for-21 from the field) reflected a rookie’s adjustment to the NBA’s pace and physicality, his defensive instincts and playmaking flashes stood out. Most notably, Flagg’s first NBA bucket—a powerful transition dunk—set the tone for his aggressive approach.

Kidd’s Vision: “Point Coop” and Versatility

With Kyrie Irving sidelined as he recovers from a torn ACL, and D’Angelo Russell expected to fill in at point guard, Kidd has hinted that Flagg will see ample time initiating the offense. The Mavericks envision “Point Coop” as a real option, leveraging Flagg’s ability to create for teammates and read the game at high speed.

“He did that at Duke and also in high school, so you get to see it tonight. He’s going to have some mistakes. We all did. But his poise as an 18-year-old is incredible,” Kidd remarked.

Flagg’s versatility is central to Dallas’s plans. Projected to start at small forward alongside veterans Anthony Davis and Klay Thompson, Flagg’s skillset allows him to operate anywhere from the wing to the point, giving the Mavericks a dynamic new dimension.

His willingness to defend, rebound, and facilitate fits seamlessly into Kidd’s system and the team’s immediate goal of contending, not rebuilding, after their blockbuster offseason moves.

Early Challenges and High Expectations

Flagg’s debut was met with both excitement and scrutiny. The packed Thomas & Mack Center buzzed with anticipation, and while Flagg admitted postgame that his performance was “not up to standard,” he remained focused on improvement. Analysts and coaches alike noted his ability to impact the game even on an off shooting night—whether through hustle plays, timely blocks, or unselfish passing.

The Mavericks, fresh off a dramatic roster overhaul, are betting that Flagg’s all-around game and competitive drive will accelerate his transition to the NBA. With Kidd’s endorsement and a clear pathway to meaningful minutes, Cooper Flagg is poised to become one of the most closely watched rookies of the 2025–26 season and a key figure in Dallas’s pursuit of immediate success.
