Cooper Flagg's first NBA Summer League game started with Bronny James hitting two shots over the No. 1 pick out of Duke. A few minutes later Flagg welcomed himself to the NBA with a fast-break dunk in traffic that looked about as easy as any of his dunks against a random ACC team.

Cooper Flagg strolled into UNLV’s Thomas and Mack Center at 4:17 p.m. for his Summer League debut, wearing Dallas Mavericks gear, bright white New Balance shoes, and an emotionless look on his face as he passed through security.

The anticipation is palpable as former Duke Blue Devils star and No. 1 overall pick Cooper Flagg prepares to make his Summer League debut on Thursday night for the Dallas Mavericks in a highly anticipated matchup against Bronny James and the Los Angeles Lakers.
