LAS VEGAS — He missed 16 of 21 shots, including all five attempts from deep, and airballed his first and final shots. And those who saw his NBA 2K26 Summer League debut still came away with a consensus gut feeling: Cooper Flagg is right on pace to be a problem.

Cooper Flagg called his NBA Summer League debut “one of the worst games of my life” after shooting 5-of-21 from the field.

All eyes were on Cooper Flagg on Thursday, as he officially took the NBA stage for the first time. After being selected with the No. 1 overall pick in the 2025 NBA draft by the Dallas Mavericks, Flagg played in his first NBA Summer League game against Bronny James and the Los Angeles Lakers.
