Thursday night’s matchup between Cooper Flagg and the Dallas Mavericks and Bronny James and the Los Angeles Lakers was the fourth-most-watched Summer League game ever, per ESPN.

The hottest ticket for Day 1 of the NBA Las Vegas Summer League will be the highly anticipated matchup between the Dallas Mavericks and the Los Angeles Lakers, as No. 1 overall pick Cooper Flagg makes his debut against Bronny James' squad.

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.
