"He is a top-five talent and player all-time at Duke, likely top-two," said a player who helped the Blue Devils win the 2010 national championship. "All-time starting five? I would probably say Flagg is the sixth man [because he lacks the team achievements]. If I had to pick a top five, however, it would be hard to keep him out."

The Duke Blue Devils went on a great run during the 2024-25 college basketball season. Led by Cooper Flagg, the storied program made it all the way to the Final Four before being eliminated by the Houston Cougars.

Now, after averaging 20.5 points across two impressive Summer League games, Flagg is set to join a veteran-laden Mavericks roster that features Anthony Davis, Klay Thompson, D’Angelo Russell, and, once healthy, fellow Duke alum Kyrie Irving.
