Dallas Mavericks forward Cooper Flagg confirmed he has grown taller this offseason, measuring 6'10" without shoes during Friday's media day. He said he was 6'9" last year and may now reach 6'11" without footwear, putting to rest speculation about his physical development. Flagg addressed reporters after a season where he led Dallas in points rebounds assists and steals despite the team's struggles.

Flagg stated plainly that he gained height over the summer, noting his measurement without shoes has increased from last season. He made the announcement during the Mavericks' annual media availability, directly responding to rumors that had circulated since the end of the 2025-26 campaign. His comments came as the team prepares for a year with added expectations following Kyrie Irving's return from ACL surgery.

The Mavericks need Flagg to take another leap after a rookie season where he carried the offensive load amid injuries to Irving and Anthony Davis. Dallas finished 26-56 last year, with Flagg shouldering heavy usage as the only consistently available scorer. His increased size could help him finish better in the paint and defend multiple positions, easing the burden on Irving when he returns to full health.

Flagg aims to improve his three-point shooting after shooting below 30% from deep last season, though he excelled at the free-throw line. If he reaches league-average three-point accuracy, analysts believe he could reach All-Star level alongside Irving. Dallas showed flashes of potential with a 149-128 win over the Chicago Bulls on April 13 2026, though their recent form stands at 1W-4L over the last five games including losses to the Phoenix Suns Milwaukee Bucks Golden State Warriors and New Orleans Pelicans.
