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.

The Dallas Mavericks look to be a big team next season. They already had a large frontcourt with Anthony Davis at power forward and the rotating center combo of Dereck Lively II and Daniel Gafford, but that was only emphasized when they won the Draft Lottery and selected Cooper Flagg, the consensus top player in the class.
