Cooper Flagg announces growth spurt ahead of 2026–27 NBA season

Cooper Flagg made an announcement during the Dallas Mavericks’ media day: he says he has grown taller ahead of the new NBA season. The club is keen on his progress on the court, and any physical change could affect how he is used during the championship.

According to Bleacher Report, Flagg said that after last season’s measurements of 6’9″, he has now grown an inch to reach 6’10”. He said the official measurements were taken on Thursday and were done without shoes.

This growth, with Flagg still just 19 years old, is positive news for the player and the Mavericks; the added height could make him harder to defend and expand his impact near the basket in his second NBA season. Flagg remains the reigning Rookie of the Year.

Details of the measurements and their implications have been reported in full by Bleacher Report.
