Cooper Flagg reached another early-career milestone Tuesday night, recording his fifth career 30-5-5 game in Dallas’ contest with the Los Angeles Lakers, the Mavericks’ public relations account announced. The performance moved the 19-year-old past Luka Dončić, who had four such games as a teenager, into second place on the NBA’s all-time list for 30-5-5 games by a teenager. Only LeBron James, with 11, ranks ahead of him.
The Mavericks’ brief post on X noted Flagg’s achievement without providing his full line for the evening; by definition, a 30-5-5 game means the player reached at least 30 points, five rebounds and five assists. The milestone underscores how quickly Flagg, the No. 1 overall pick, has established himself as an offensive fulcrum in Dallas despite his youth.
Flagg’s five 30-5-5 performances this season also outnumber the combined total of the rest of this year’s rookie class, who have managed three such games between them, according to the Mavericks’ release. That gap highlights how Flagg’s statistical profile — scoring punch coupled with playmaking and rebounding — sets him apart from his peers in the 2025-26 rookie crop.
The surge builds on a string of eye-catching performances that have kept Flagg in early Rookie of the Year discussions. Less than a week earlier he poured in a franchise-record 51 points against the Orlando Magic, becoming the youngest player in NBA history to reach 50 in a game and further intensifying the debate over the league’s top rookie honors. That outing and continued big games like Tuesday’s have reinforced his reputation as one of the NBA’s most intriguing young talents.
Historical comparisons to players like Dončić and James are inevitable but tell only part of the story. Dončić’s four 30-5-5 games as a teenager came amid his own rapid ascent in Dallas; Flagg’s similar benchmark at a younger physical and professional stage suggests a different developmental arc, one being watched closely by league executives, coaches and fans alike. LeBron’s 11 teenage 30-5-5 games remain a distant but meaningful standard of sustained dominance at a young age.
Dallas has leaned on Flagg’s versatility as it navigates a season of competing priorities, blending his scoring with the veteran presence on the roster. How he sustains this level of production over the coming months — and whether the Mavs can translate his individual milestones into deeper postseason traction — will shape both his early legacy and Dallas’ immediate outlook. For now, Flagg’s latest 30-5-5 game cements his place among the most statistically prolific teenagers in NBA history.
