Flagg's arrival has been the talk of Summer League. The 6-foot-8 Wooden Award winner, 18, will be joined on Dallas' offseason roster by two-way rookie point guard Ryan Nembhard and two-way shooting guard Miles Kelly, 2024-25 Mavericks rookie, and 7-foot-5 Texas Legends center Jamarion Sharp.

Flagg is the only draft pick for the Mavericks, but he's certainly far from the only rookie on the Summer League roster. The Mavericks have several rookies flanking Flagg in Las Vegas, most notably former Auburn guard Miles Kelly and former Gonzaga guard Ryan Nembhard.
