Cooper Flagg, a basketball prodigy from the quiet town of Newport, Maine, recently showcased his skill in a major way—going toe-to-toe with top NBA players in a scrimmage while still just a teenager. Playing for the USA Select Team, Flagg stood out on the court among elite players, proving himself with moves and resilience that left a lasting impression on spectators, including NBA officials, media, and his parents, Kelly and Ralph Flagg.
At just 17 years old, Flagg played alongside NBA professionals as a special addition to the USA Select Team, assembled to help prepare Team USA for the Olympics. While other players his age are navigating high school sports, Flagg was competing against athletes like LeBron James, Stephen Curry, and Anthony Davis. His standout performance not only confirmed his talent but also ignited excitement among Duke University’s basketball staff, who look forward to seeing him develop as part of their team in the near future.
Early Life in Newport, Maine
Flagg’s journey began in Newport, Maine, a town with a population of around 3,200, far removed from the bustling basketball circuits of major cities. Though small, Newport is where Flagg’s foundation in basketball was laid, nurtured by his parents, both of whom share a strong connection to the sport. The Flagg family instilled in Cooper a passion for the game and a respect for teamwork, attributes that would define his approach on the court.
Growing up in Newport, Flagg spent countless hours practicing with his family. His mother, Kelly, had been a celebrated player herself, starring for the University of Maine. Her love for the Boston Celtics, particularly their 1985-86 team, played a major role in how she introduced her sons to basketball. Kelly emphasized the Celtics’ focus on selflessness, defense, and smart team play. This influence from such a historic NBA team would later shape Flagg’s perspective on the game and his on-court decisions.
Family Influence and Celtics Legacy
Kelly’s childhood memories are filled with weekends gathered around the television to watch the Celtics play, turning down the volume to listen to radio announcer Johnny Most narrate the action. For her, the 1985-86 Celtics represented the purest form of basketball—a team that prioritized smart passing, unselfish plays, and relentless defense. Players like Larry Bird and Kevin McHale became household names, and Kelly shared these inspirations with her sons.
To bring the Celtics' influence into their home, Kelly and Ralph bought DVDs of classic Celtics games for Cooper to watch. Starting in elementary school, Flagg would sit transfixed, observing the Celtics' crisp passes, tenacious defense, and focus on team play. He took to heart the values his parents emphasized, studying not only how to score but also how to create opportunities for teammates. Kelly’s deep commitment to the sport and Ralph’s supportive presence further nurtured Flagg’s talent, leading him to excel beyond the expectations for a small-town athlete.
Competing Beyond His Years
Flagg’s journey in basketball progressed quickly. From a young age, he played against older competitors—first facing players in elementary school who were several years his senior, then moving on to face former college players in his early teens. His skills developed rapidly, and he became known for his advanced footwork, situational awareness, and unselfish play style, even earning his first college scholarship offer before he began high school.
By his freshman year, he was a standout at Nokomis Regional High School, helping the team secure a state championship. His performance was nothing short of impressive, leading to him being named the Maine Gatorade Player of the Year. Flagg’s rise quickly became a source of pride for the community, filling local gymnasiums with fans eager to see Newport’s young star in action.
Guidance from Mentors and NBA Connections
As Flagg’s talent became undeniable, experienced coaches and former players began to take notice. One pivotal mentor, Brian Scalabrine, an 11-year NBA veteran, invited Flagg to intense training sessions where he played with and against some of Boston’s best young players. Scalabrine, known for his competitive spirit, recognized Flagg’s potential from the first session. Under Scalabrine’s mentorship, Flagg refined his ability to make high-pressure plays, handle physicality, and execute quick decisions—all traits essential for success in professional basketball.
Flagg’s trainer, Matt MacKenzie, also played a crucial role in his development. Through rigorous drills and one-on-one guidance, MacKenzie helped him refine his shooting, footwork, and agility. MacKenzie’s influence helped Flagg stay grounded and focused on constant improvement, traits that set him apart from his peers.
Transition to Montverde Academy and National Stage
After his freshman year, Flagg took another leap, transferring to Montverde Academy, a Florida school known for producing elite basketball talent. At Montverde, Flagg played under Coach Kevin Boyle, whose experience developing NBA players like Kyrie Irving and Ben Simmons provided an ideal environment for Flagg to reach new heights.
At Montverde, Flagg’s role on the team highlighted his versatility. While often one of the younger players on the court, he adapted quickly, consistently making an impact with his defense, assists, and scoring when needed. His selfless play style caught the attention of national scouts, and he was soon invited to participate in prominent tournaments, including Nike’s EYBL Peach Jam, where he competed against top high school players.
Dominance on the AAU Circuit
Flagg’s performances on the AAU circuit solidified his reputation as one of the most promising young players in the country. Playing for Maine United, he posted remarkable stats, averaging double-doubles and triple-doubles in games against top-tier competition. His unselfish play, combined with his defensive prowess and sharp instincts, set him apart, drawing praise from spectators and even seasoned NBA players who attended the games.
NBA stars like LeBron James and Chris Paul took notice, expressing admiration for Flagg’s team-oriented style. This recognition from established professionals added to his motivation, reinforcing the idea that his dedication to fundamentals and unselfish play resonated with those at the highest levels of the sport.
Commitment to Duke and Future Aspirations
In August 2023, Flagg made a significant decision to reclassify, aligning himself with the 2025 NBA draft class and committing to Duke University. Choosing Duke over other prestigious programs, Flagg showed a clear vision for his development, aligning with a team known for producing NBA-ready players. Duke coaches see Flagg as a unique talent whose play style and values match their program’s philosophy, setting the stage for him to grow both as an athlete and as a leader.
His debut with Duke offered a glimpse into his future impact. Playing against the University of Maine, Flagg displayed his signature style, focusing on making smart plays and supporting his teammates. His contribution on defense and his skill in creating scoring opportunities affirmed his place on the team and reinforced the high expectations surrounding his journey.
