Cooper Flagg was the No. 1 overall pick in the 2025 NBA Draft and now he is set to make his NBA Summer League debut against Bronny James and the Los Angeles Lakers.
While fans may know about the generational prospect, some fans may be surprised to learn that Flagg has a twin brother — a fact that makes his story even more intriguing.
How Many Brothers Does Cooper Flagg Have?
Flagg has two siblings: an older brother, Hunter Flagg, and a twin brother, Ace Flagg. Hunter played high school basketball and is just a few years older than his twin brothers.
Ace is an aspiring pro basketball player like his brother. Reports indicate he has committed to the University of Maine and will play for the Black Bears. Given that the Flagg family is from Maine, this makes his commitment extra special.
Cooper and Ace played together in high school, leading Nokomis Regional High School to a state championship and Montverde Academy to a national championship. While Cooper reclassified to enter college early, Ace went on to play at Greensboro Day School, helping them win a state championship as well.
Because Ace has not received much playing time, it’s difficult to determine how he compares to Cooper at this stage. However, at the moment, he isn’t currently on the NBA’s radar. For now, all eyes are on Cooper and whether he can transition successfully to the NBA.
The boys’ mother, Kelly Flagg, was also a college basketball player for Maine and is considered a local sports legend. One can only imagine the pride in seeing her children follow in her footsteps.

The Bronny vs. Flagg matchup drives these sky-high prices. Flagg is arguably the most hyped-up American prospect out of the NBA Draft since Zion Williamson in 2019.
Despite not having a resume like Flagg’s, James draws attention as the son of the league’s biggest star, LeBron James. Plus, his father/teammate may attend the game to cheer for his son, adding extra excitement.
The Lakers vs. Mavericks matchup carries another intriguing storyline: the Luka Dončić-Flagg connection. Dallas traded Dončić, Maxi Kleber, and Markieff Morris to the Lakers during the 2024-25 season, receiving Anthony Davis and Max Christie in return.
The trade caught everyone off guard. Many analysts criticized the Mavericks, saying they lost their prospects of a great future. However, despite having just a 1.8% chance, Dallas got the first overall pick and selected Flagg, who many consider the franchise’s future.
Flagg seems excited to play in the Summer League, particularly with his new teammates.
“I think it’s just a great group of guys to have as teammates for Summer League,” Flagg said after the first day of Summer League practice.
“A lot of teams can get caught up just trying to figure themselves out or playing a lot of iso ball. But I think we have a really good group that wants to play the right way and showcase a strong, team-oriented brand of basketball,” Flagg added.
While Bronny vs. Flagg grabs casual fans’ attention, hardcore fans will also focus on Flagg vs. Dalton Knecht. Knecht was the 17th pick in the 2024 NBA Draft. Though Flagg holds the edge in almost all aspects, Knecht has one year of NBA experience on his side.
The Lakers had planned to trade Knecht to the Charlotte Hornets for Mark Williams in February, but the deal fell through. With a strong showing in the Summer League, Knecht will look to prove to the front office that he belongs in the Lakers’ long-term plans.
