Monday was a big day for Duke star Cooper Flagg as he learned of his (likely) future home for the foreseeable future. To start the day at the NBA Draft Combine he measured nearly an inch taller than he did before his one-and-done Blue Devils season.

The NBA's predraft season is in full swing as the league held its draft lottery Monday, with the Dallas Mavericks winning the No. 1 pick, and the chance to select projected top pick Cooper Flagg -- an opportunity a source told ESPN Tuesday that the Mavericks intend to see through during the draft on June 25-26 in Brooklyn, New York.

Longtime NBA agent Rich Paul doesn't see the Mavericks trading Cooper Flagg after securing the No. 1 overall pick.
