Flagg said at Mavericks Media Day that he has grown from his listed height of 6-foot-9 last season to an official barefoot measurement of 6-foot-10, Marc Stein of The Stein Line reports.
The 19-year-old's continued physical development gives him even more positional size heading into his second NBA season after an impressive rookie campaign. The sky is the limit as Flagg will now benefit from playing alongside a healthy Kyrie Irving in 2026-27.
