Teenager Flagg scores 49 points, breaks 46-year record in loss

Cooper Flagg turned in a performance that won't happen again for decades — then watched his team lose anyway.

The 19-year-old Mavericks rookie scored 49 points in a single game this week, breaking the 46-year-old record for most points ever scored by a teenager in an NBA contest. Cliff Robinson had held that mark at 45 points since 1980. Flagg shot 20-of-29 from the field and pulled down 10 rebounds in the same game. By any measure, it's a historic night.

Except the Charlotte Hornets won 123-121.

Kon Knueppel, Flagg's former Duke teammate from just a season ago, hit two free throws with 4.1 seconds remaining to seal it. Knueppel finished with 34 points of his own — a career high and a rookie record for the Hornets — including eight three-pointers. The two had shared a locker room as Duke freshmen in the 2024-25 season before both entering the NBA draft. On this night, they were on opposite sides of a game that will be remembered for Flagg's brilliance and his heartbreak in equal measure.

Brandon Miller added 23 points for Charlotte, his ninth straight game with at least 20 points, while LaMelo Ball contributed 22 points with six three-pointers. For Dallas, Klay Thompson scored 16 points off the bench but couldn't help the Mavericks avoid their third straight home loss.

Flagg's 49-point night represents something worth sitting with: a teenager performing at a level we might not see again for half a century. The gap between his individual performance and the final score is the kind of contradiction that defines sports — sometimes the most memorable moments happen in losses, and sometimes the record books capture only part of the story.
