Cooper Flagg completed his first year in the NBA with the Dallas Mavericks after being selected as the top overall pick in the 2025 draft. The forward had a productive rookie campaign in the 2025-26 season and earned the Kia NBA Rookie of the Year award.
Flagg averaged 21.0 points, 6.7 rebounds, and 4.5 assists per game. He led all first year players in scoring and stood out with several high scoring performances, including a 50-point game as a teenager. His play helped the Mavericks in several areas, and he earned first place votes on most ballots for the Rookie of the Year award. He finished ahead of former college teammate Kon Knueppel in a close race.
The NBA also named Flagg to the All-Rookie First Team. He received first place votes on every ballot from a panel of writers and broadcasters. At 19 years old, he became one of the youngest players in league history to earn that honor, behind only LeBron James in that category.
Flagg played at Duke before entering the draft. His size, skill set, and production in his first season connected him to early career stars. The Mavericks have begun building around him as a central part of their plans. Team officials and observers have noted his quick adjustment to the professional level.
In the current offseason, Flagg has been linked to summer league activities and team preparations. His rookie year has set expectations for continued growth with the Mavericks.
