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.

Cooper Flagg appeared in his first pro game on Thursday night when the Dallas Mavericks played the Los Angeles Lakers at NBA Summer League. During the game (which the Mavs won by a score of 87-85), Flagg made a shot over Bronny James that got a lot of views on social media.

Perhaps the biggest Summer League matchup of the year is here as Cooper Flagg and Dylan Harper prepare to go head-to-head in Las Vegas. The two top prospects were the No. 1 and No. 2 picks in the 2025 NBA Draft.
