Cooper Flagg Makes NBA History! 36 Points vs Celtics at 19 Years Old | Full Highlights & Analysis (2026)

A Maine Prodigy Shatters NBA Records Against His Childhood Idols! It's not every day a player lights up the scoreboard against their favorite team, but Dallas Mavericks rookie Cooper Flagg did just that, etching his name in NBA history.

In a thrilling matchup against the Boston Celtics on Tuesday, Cooper Flagg, a proud native of Newport, Maine, not only led all scorers but also achieved a remarkable feat. He poured in a game-high 36 points, complemented by 9 rebounds, 6 assists, and 2 blocks. This performance was particularly poignant as the Celtics were the team he grew up cheering for.

But here's where it gets truly historic: At just 19 years and 44 days old, Flagg has become the youngest player in NBA history to score 30 or more points in three consecutive games. This incredible scoring streak includes a personal-best 49 points against the Charlotte Hornets on January 29th, followed by 34 points against the Houston Rockets just two days later. Imagine the pressure of those moments, and he delivered!

And this is the part most people miss: Flagg's dominance extends beyond just scoring. He's now the fourth teenager ever in the NBA to achieve multiple games with at least 35 points, 5 rebounds, and 5 assists. He joins an elite club that includes legends like LeBron James (who accomplished this four times), and Kevin Durant and Luka Doncic (each doing it twice). Flagg himself had a 42-point, 7-rebound, 6-assist outing against the Utah Jazz on December 15, 2025, showcasing his all-around impact.

However, the fairytale ending wasn't complete on the scoreboard. The Celtics ultimately triumphed over the Mavericks with a 110-100 victory in Dallas. For Boston, All-Star Jaylen Brown was a force, recording a double-double with 33 points and 11 rebounds.

Adding to Flagg's stellar week, he was also named the Western Conference Rookie of the Month for January, marking a perfect three-for-three in earning this award to start his professional career. Meanwhile, Jaylen Brown was recognized as the Eastern Conference Player of the Month for January.

In other NBA news, the Celtics made a significant trade on Tuesday, acquiring veteran center Nikola Vucevic from the Chicago Bulls. This move, which sent guard Anfernee Simons to Chicago, adds considerable experience to Boston's roster.

Flagg's next opportunity to extend his scoring surge will be on Thursday when the Mavericks host the San Antonio Spurs. Will he continue this incredible run?

What do you think? Is Cooper Flagg's early success a sign of a future superstar, or is it too soon to tell? Does his connection to the Celtics add an extra layer of narrative to his historic achievements? Share your thoughts in the comments below!
