Cooper Flagg made his highly anticipated NBA Summer League debut on July 10, 2025, leading the Dallas Mavericks to an 87–85 victory over the Los Angeles Lakers in Las Vegas. The game was a marquee matchup, featuring Flagg, the No. 1 overall pick in the 2025 NBA Draft, and Bronny James, son of LeBron James.

Flagg and James were the star power duo in today’s Summer League games. It was the most expensive summer league ticket of all time with lower bowl seats selling for $650 ($A987) while if you wanted to be courtside it would set you back $2,500 ($A3797). Pretty good value for seeing 5/21 and 2/8 shooting displays!
