Cooper Flagg, the highly touted rookie drafted by the Dallas Mavericks, is opening up about the mental and physical challenges he faced during his debut NBA season. Despite flashes of his immense talent, Flagg's first year was marred by the Mavericks' injury-plagued roster and organizational turmoil, forcing the 19-year-old to adapt quickly to the rigors of professional basketball.

Why it matters

Flagg's experience is a case study in how a team's structural weaknesses can impact a young player's development. The Mavericks' struggles to field a stable, veteran-led roster placed added pressure on Flagg to shoulder a heavy load, testing his mental resilience and on-court decision-making.

The details

In three separate incidents, police said Walker Reed Quinn has been damaging Waymo vehicles since July by removing and swinging his belt, placing a cone on the dome and sensors of the car, damaging the tires and driver's side mirror, and stomping on the windshield.

  • Flagg was drafted by the Mavericks in the 2025 NBA Draft.
  • The 2025-26 NBA season was Flagg's rookie campaign with the Mavericks.
