Duke Blue Devils standout Cooper Flagg has been the talk of the league since the NBA draft lottery was finalized. With the Dallas Mavericks shockingly winning the No. 1 pick, he's expected to join forces with Kyrie Irving and Anthony Davis to begin his career.

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.
