Mavs' Cooper Flagg says he's grown an inch, is now 6-foot-10 without shoes

Flagg, the 2025-26 NBA Rookie of the Year, is still only 19 years old. He's going to grow with the Mavericks. It turns out that maturation isn't limited to his play on the court or even his development as a leader and person.

Flagg told reporters Friday at Mavs media day that he literally grew over the past year. Listed at 6-foot-9 ahead of last season , Flagg said he's now 6-10 without shoes .

That makes him an even more imposing threat on the hardwood. Flagg could already put on a show with thundering dunks and head-turning blocks.
