For the past 15 years, Duke has had numerous freshmen make an immediate impact, including Cooper Flagg and Cameron Boozer, the consensus national player of the years the past two seasons. This coming season, the Blue Devils will have another elite freshman class, led by Joaquim Boumtje Boumtje, a 6-foot-11 forward.
On Sunday, Boumtje Boumtje led Team USA to the FIBA U17 Basketball World Cup title, defeating Serbia 107-81 in Turkiye. He had 20 points, 15 rebounds and three blocks. He was named the tournament’s Most Valuable Player after averaging 19.6 points, 10.9 rebounds and 2.1 blocks in just 22.8 minutes per game and helping the US to a 7-0 record. Boumtje Boumtje shot 59.8% from the field, connected on 17 of 32 3-pointers, made 22 of 25 free throws and helped Team USA win its games by an average of 48.9 points and improve to 58-0 all-time in the event.
Boumtje Boumtje, who turned 17 on May 30, committed to Duke in late April. He is the son of Ruben Boumtje Boumtje, a 7-foot center who started at Georgetown for three seasons before the Portland Trail Blazers selected him in the second round of the 2001 NBA draft.
The elder Boumtje Boumtje played just 44 NBA games in parts of three seasons, but he continued his career overseas, earned his masters degree in applied mathematics and statistics from Georgetown and started working for the Philadelphia 76ers in 2018. He is currently the head of league operations for the Basketball Africa League, an NBA affiliate in Senegal.
The past three years, Joaquim Boumtje Boumtje played for FC Barcelona’s U22 team in Spain. He averaged 16.1 points and 6.8 rebounds per game this past season and shot 51.1% from the field. In May, he led FC Barcelona’s U18 team to the adidas NextGen EuroLeague title and was named the tournament’s MVP after averaging 19 points, 7.5 rebounds and 3.8 assists per game.
At the FIBA tournament this past week, Boumtje Boumtje showed again why he may be the best prospect in youth basketball and should be a major contributor at Duke this season. Although he didn’t play high school basketball, he emerged as the top player on a loaded roster.
Other players who stood out for Team USA included Beckham Black and CJ Rosser, who are teammates at Southeastern Prep in Orlando, Fla. Black, a 6-foot-2 guard and the brother of Orlando Magic guard Anthony Black, was named to the All-Star Five, which is the name for the all tournament team. Black averaged 12.3 points, 8.3 assists and three steals per game. Rosser, a 6-foot-9 forward, was second on the team with 16.4 points per game and made 51.3% of his shots.
Rosser is No. 1 in the 247Sports Composite rankings for the high school class of 2027, while Black is No. 4. For Team USA, they started alongside Boumtje Boumtje, 6-foot-5 guard Jordan Page and 6-foot-9 center Erick Dampier Jr. Page, who plays for Broughton High School in Raleigh, N.C., averaged 9.8 points per game. He is the No. 13 player in the class of 2027. Dampier Jr., the son of former NBA center Erick Dampier, averaged 12.4 points and 5.7 rebounds per game. He doesn’t turn 17 until October and is the No. 5 player in the class of 2028, per the 247Sports Composite.
The other Team USA players who averaged more than 10 points per game were 6-foot-7 forward AJ Williams, the top-ranked player in the class of 2028 who averaged 14 points and 6.6 rebounds per game, and 6-foot-2 guard NaVorro Bowman Jr., the No. 17 player in the class of 2027 who averaged 11.9 points per game. Williams’s father played basketball at Vanderbilt from 1997 through 2001, while Bowman’s father played football at Penn State and spent eight seasons in the NFL as a linebacker.
While the rest of his Team USA teammates have at least one year remaining in high school, Boumtje Boumtje is headed to college this fall and could be the youngest player in Division 1. Still, he should step into Duke’s lineup right away and play major minutes for a team with national title aspirations.
The Blue Devils are No. 2 in CBS Sports analyst Gary Parrish’s latest preseason rankings. Although Cameron Boozer was selected No. 3 in last month’s NBA draft and forwards Isaiah Evans and Maliq Brown were second round picks, Duke returns center Patrick Ngongba and guards Caleb Foster, Cayden Boozer and Dame Sarr, all of whom were in the team’s rotation last season when it made the NCAA tournament’s Elite Eight. The Blue Devils nearly advanced to the Final Four, but UConn guard Braylon Mullins made a 35-footer with less than a second remaining to pull off a 74-73 comeback win.
Duke also added transfer guard John Blackwell, who averaged 19.4 points per game at Wisconsin last season, and signed top incoming freshmen in forward Cameron Williams, point guard Deron Rippey Jr. and shooting guard Bryson Howard, who were No. 4, No. 12 and No. 22 in the high school class of 2026, per the 247Sports Composite.
Boumtje Boumtje, meanwhile, was not ranked by 247Sports or other U.S.-based scouting websites because he played in Europe, but he enters college as arguably the top freshmen in the nation. And the best part for Duke? Boumtje Boumtje isn’t eligible to enter the NBA draft until 2028 because he is so young. As such, he could spend two years at Duke.
For all of Duke’s success recruiting freshmen under former coach Mike Krzyzewski and current coach Jon Scheyer, the Blue Devils last won the national title in 2015. Since then, Duke has had 22 first round NBA draft picks, including three overall No. 1 selections in Zion Williamson, Paolo Banchero and Flagg. Boumtje Boumtje is on track to be another first round pick and possibly the No. 1 overall choice. But before then, he faces high expectations at a program that is always among the nation’s best. Although Boumtje Boumtje doesn’t turn 18 until this coming season ends, he will be in the spotlight as Duke seeks to break its national title drought and bring Scheyer his first championship as a coach.
