Road to Duke
In a house three miles from the one where she would raise him, Kelly Bowman fell in love with basketball at age seven. Her father Dan affixed a hoop to a shed in their backyard in Newport, Maine — population 3,200. They played so often the grass faded into dirt. When it got dark, Dan parked a car and turned on the headlights so his daughter could keep shooting.
Kelly starred at Nokomis Regional High School, earned a Division I scholarship to the University of Maine, became team captain, and helped win three conference championships. Ralph Flagg also attended Nokomis, played at Eastern Maine Community College. They met at a community center basketball game. He couldn't stop her up-and-under move. As a wedding present, they received a crabapple tree and planted it next to the driveway hoop where their children would grow up.
In 2004, Kelly went into premature labor at 24 weeks. Twins Hunter and Ryder were born at Maine Medical Center in Portland. Hunter weighed 1 pound, 10 ounces. Ryder weighed two ounces less. Ryder died two days later. Hunter spent 109 days in the NICU. Kelly refused to leave Portland. The Ronald McDonald House became the family's home for nearly four months.
Cooper and Ace Flagg — fraternal twins — were born on December 21, 2006, premature but healthy enough to go home for Christmas. The household in Newport was organized entirely around basketball. Kelly coached the Nokomis girls' varsity team. The boys grew up in the gym. Driveway games ended only when someone ran inside bleeding. Cooper played in a fourth-grade recreation league as a second-grader. He was already the best player on the court.
In March 2022, all three Flagg brothers — Hunter as a senior, Cooper and Ace as freshmen — led Nokomis to the school's first-ever state championship. Cooper scored 22 points and grabbed 16 rebounds in the title game. He became the first freshman in Maine history to be named Gatorade Player of the Year, averaging 20.5 points, 10.0 rebounds, 6.2 assists, 3.7 steals, and 3.7 blocks per game. The stat line was absurd — a player leading his team in every category as a fourteen-year-old in a state not known for producing elite basketball talent.
Then he left home. Cooper and Ace transferred to Montverde Academy in Montverde, Florida — the national prep powerhouse that had produced Cade Cunningham, Scottie Barnes, and D'Angelo Russell. The Flagg family relocated from Newport to Florida to keep the family together. At Montverde, Cooper's profile went from regional curiosity to global phenomenon. He was selected for the USA Basketball U17 team and won gold at the FIBA U17 World Cup, grabbing 17 rebounds against Spain in the gold medal game. He was named USA Basketball Male Athlete of the Year — at fifteen years old.
He reclassified from the Class of 2025 to 2024, skipping his junior year entirely. As a senior at Montverde, he was the consensus No. 1 recruit in the nation — the most hyped prospect since LeBron James, according to some analysts. He was named the Naismith High School Player of the Year, McDonald's All-American, and Jordan Brand Classic MVP. Every major program in the country recruited him.
Cooper Flagg planned to announce his Duke commitment on October 27, 2023. He delayed three days after the Lewiston, Maine, mass shootings — 18 people killed in a bowling alley and a bar in his home state. He committed to Duke on October 30. He signed a shoe deal with New Balance because two of the company's factories are located near Newport. He became the first men's college basketball player ever sponsored by Gatorade. In the summer of 2024, he was invited to join the USA Select Team at age seventeen — a practice squad for the Olympic team — and scored up to 17 points in scrimmages against LeBron James, Stephen Curry, and Kevin Durant. KD's assessment: 'He's 17 years old playing like a veteran.'
At Duke
Cooper Flagg enrolled at Duke in June 2024, arriving early for summer practices, and immediately became the most scrutinized freshman in the history of the program. His college debut on November 4, 2024, felt scripted: Duke against the University of Maine — his mother's alma mater. He scored 18 points with 7 rebounds, 5 assists, and 3 steals in a 96-62 victory. Kelly Flagg watched from the stands.
What followed was the single greatest freshman season in Duke basketball history, and arguably the best one-and-done season in college basketball. Flagg averaged 19.2 points, 7.5 rebounds, 4.2 assists, 1.4 steals, and 1.3 blocks per game — leading Duke in all five major statistical categories. No freshman in Wooden Award history had ever done that. He shot 48.3 percent from the field, 37.4 percent from three, and 83.6 percent from the free throw line. He scored 709 points, 20th in Duke single-season history. He was named ACC Rookie of the Week a record twelve times.
The signature game came on January 11, 2025, against Notre Dame: 42 points on 11-of-14 shooting, 4-of-6 from three, 16-of-17 from the line, with 6 rebounds and 7 assists. It was the Duke and ACC freshman single-game scoring record. He became the first ACC player in 25 years to record 500 or more points, 100 or more assists, and 30 or more blocks in a single regular season.
Duke went 29-4 overall and 19-1 in ACC play, winning both the regular season and ACC Tournament championships. In the NCAA Tournament, Flagg scored 14, 18, 30, and 16 points through four rounds. The Final Four semifinal against Houston on April 5, 2025, was his masterpiece and his heartbreak: 27 points, 7 rebounds, 4 assists, 3 blocks, and 2 steals — the first player since 1986 to lead his team in all five statistical categories in a Final Four game. Duke lost 70-67. The championship that felt inevitable slipped away in the final minutes.
The awards arrived in a wave. Naismith Award. Wooden Award. Associated Press Player of the Year. USBWA Player of the Year. NABC Player of the Year. ACC Player of the Year and ACC Rookie of the Year — the fourth player in conference history to win both in the same season, joining Zion Williamson, Marvin Bagley III, and Jahlil Okafor. Consensus first-team All-American. Jon Scheyer's first No. 1 recruit had delivered one of the five best one-and-done seasons in college basketball history.
After Duke
The Dallas Mavericks selected Cooper Flagg with the first overall pick in the 2025 NBA Draft on June 25, 2025. He was 18 years and 186 days old — the second-youngest No. 1 pick in NBA history, eight days older than LeBron James had been in 2003. He was signed on July 2.
Before the draft, Flagg did not fly to Los Angeles for celebrity workouts or media tours. He went home to Maine. He trained at a Division III gym at Colby College in Waterville with his twin brother Ace. He drove to Newport to watch his classmates graduate from Nokomis Regional — the ceremony that should have been his if he hadn't reclassified. The gesture said everything about who he was: the No. 1 pick in the world, sitting in the audience at a rural Maine high school graduation, watching the people he grew up with walk across a stage he never got to cross.
In December 2024, during his Duke season, the Flagg family had donated $10,000 to the Ronald McDonald House in Durham. Kelly cried telling the story of Hunter and Ryder — the twins born premature in Portland, one who survived 109 days in the NICU, one who didn't survive two. The donation was the family's way of honoring the place that gave them a home during the worst days of their lives.
Flagg's Dallas arrival carried a weight beyond basketball. The Mavericks had traded Luka Dončić the previous season, and Flagg was inheriting the face-of-the-franchise mantle alongside Kyrie Irving and Anthony Davis. He was transitioning from forward to a primary ball-handling role — a positional experiment that few No. 1 picks have attempted as rookies.
Where Is He Now
Cooper Flagg's NBA rookie season has confirmed everything the hype suggested and revealed dimensions no one predicted. Through 72 games, he is averaging 20.4 points, 6.6 rebounds, and 4.6 assists per game — all ranking in the top five among rookies, with his scoring average 33rd in the entire NBA. He is outscoring Karl-Anthony Towns and DeMar DeRozan.
The record book has already been rewritten. On December 15, 2025, Flagg scored 42 points in an overtime loss to the Utah Jazz, becoming the youngest player in NBA history to score 40 in a game — 94 days younger than LeBron James was when he did it. On January 29, 2026, he dropped a career-high 49 points against the Charlotte Hornets — the most points ever scored by a teenager in NBA history, surpassing Cliff Robinson's 45 in 1980. On Christmas Day, he had 27 points, 6 rebounds, and 5 assists against the Golden State Warriors, becoming just the third rookie ever to post a 25/5/5 line on Christmas, joining Oscar Robertson in 1960 and Pete Maravich in 1970. He has recorded eight 30-point games, breaking a three-way tie with Kevin Durant and Luka Dončić for third-most by a teenager in NBA history, trailing only LeBron James and Carmelo Anthony.
He was selected for the 2026 NBA All-Star Game in Los Angeles — the youngest All-Star in Mavericks franchise history. In March, returning from a left midfoot sprain that sidelined him for eight games, he erupted for 20 first-half points in Portland — his eleventh career 20-point half, more than the rest of the entire rookie class combined. The Mavericks' season has been difficult — 24-50, heading toward missing the playoffs — but Flagg has been the steady bright spot, the reason Dallas fans believe in the future. He ranks second on the NBA rookie ladder behind fellow Duke Blue Devil Kon Knueppel.
Mavericks fans have adopted a tradition during the national anthem: when the lyrics reach 'that our flag was still there,' they shout his surname. It is a small, wonderful, distinctly American detail — the kid from Newport, Maine, whose last name is woven into the fabric of the national anthem at every Mavericks home game.
Cooper Flagg is nineteen years old. Twin brother Ace plays at the University of Maine. Older brother Hunter is studying sports management. Ryder, who lived for two days in 2004, is remembered every time the family walks through the doors of a Ronald McDonald House.
Kelly Bowman Flagg — who shot baskets by headlight in a town of 3,200 people, who captained Maine, who planted a crabapple tree next to the driveway hoop — watched her son become the No. 1 pick. Ralph watched beside her. The crabapple tree is still there. The headlights are still on. Cooper Flagg is just getting started.
