DALLAS (Oct. 17, 2026) – The Dallas Mavericks announced today that they have exercised the third year rookie scale option on forward/guard Cooper Flagg.
Flagg (6-9, 228) averaged 21.0 points, 6.7 rebounds, 4.5 assists, 1.2 steals, 0.9 blocks and 33.5 minutes per game in 70 games (all starts) last season en route to being named the 2025-26 Kia NBA Rookie of the Year. At 19 years, 112 days, Flagg became the second-youngest player in NBA history to garner Rookie of the Year honors behind LeBron James (19 years, 106 days).
The Duke University product led the Mavericks in total points (1,473), rebounds (466), assists (316) and steals (84) in 2025-26. He finished as the only player in the entire NBA to lead his team in each of the four categories and joined Michael Jordan as the only rookies in league history to do so. Flagg averaged 22.6 points, 6.9 rebounds, 5.4 assists, 1.2 steals and 1.2 blocks after the All-Star break, finishing as the only player across the entire NBA to average at least 20.0 points, 6.0 rebounds, 5.0 assists, 1.0 steals and 1.0 blocks following the break.
Flagg (19 years, 103 days) became the youngest player in NBA history to score 50-plus points with his 51point performance against the Orlando Magic on April 3, breaking his own record for the most points by a teenager in NBA history (49, vs. Charlotte, Jan. 29). He followed with a 45-point outing against the Los Angeles Lakers on April 5 to join Wilt Chamberlain as the only rookies in NBA history to total 96-plus points over any two-game span.
