Soon after the season, Flagg declared for the NBA Draft, along with Knueppel and Maluach. While Knueppel and Maluach are projected lottery picks, Flagg, who originally committed to Duke as the No. 1 overall recruit is expected to keep that tag and be drafted No. 1 in the draft.

Cooper Flagg is the best player from Duke in the 2025 NBA Draft. But he's going No. 1 — another Duke star could change everything as he rockets up draft boards.

As a help defender, Flagg shines. His quick twitch muscles sync up perfectly with his brain to allow him to fly in and block shots at the rim and knock away pass attempts in the gaps. Cooper has a plus wingspan and a sturdy frame and has mastered his physical gifts to be come a special off-ball defender.
