Cooper Flagg won the Naismith and Wooden Awards as a college freshman at Duke last season.

Last summer he became the second youngest player behind LeBron James to be selected No. 1 overall in the NBA Draft.

And now the Dallas Mavericks forward has been named NBA Rookie of the Year.

The 6-foot-9 rookie beat out his former Duke teammate Kon Knueppel of the Charlotte Hornets by 26 points. It was the second smallest gap since the current voting format began in 2002-03, behind only a 15-point gap in 2021-22.

Flagg, 19, is the second youngest player after James to win the award, and only the second rookie after Michael Jordan to lead his team in points, rebounds, assists and steals.

With the Mavericks having traded away Luka Doncic in 2025 and then Anthony Davis this year, Flagg has quickly become the face of the franchise.

Here are some of Flagg’s accomplishments this season per the NBA.

• Led all rookies in scoring (21.0 ppg) and ranked fourth in rebounding (6.7 rpg), second in assists (4.5 apg) and steals (1.20 spg), and fifth in blocks (0.91 bpg) in 70 games
• Joined Michael Jordan as the only rookies to lead their team in total points (1,473), rebounds (466), assists (316) and steals (84) since steals were first recorded in 1973-74
• Youngest player in NBA history to score at least 50 points in a game (51 vs. Orlando Magic on April 3)
• First rookie to have four or more games with at least 40 points since Allen Iverson in 1996-97
• Second-youngest Kia NBA Rookie of the Year winner (19 years, 112 days as of April 12, the final day of the regular season), behind only LeBron James (19 years, 106 days in 2003-04)
