When news broke that Dallas Mavericks rookie Cooper Flagg and Duke women's basketball center Arianna Roberson were officially a couple, it connected two of the most promising young talents in American basketball. But Roberson is far more than just a partner to a rising NBA star. She's a force in her own right, with a story rooted in San Antonio, Texas, and a family legacy that runs deep in the sport.
Here are five things to know about the 6'4" center who anchors the Blue Devils' frontcourt.
1. A Dominant Presence in the Paint
Born on January 2, 2006, in San Antonio, Arianna Jalisa Roberson brings elite physical tools to the court. At 6'4", she combines strength under the basket with lateral quickness, making her one of the most versatile interior defenders in the ACC. Her ability to protect the rim and switch onto guards sets her apart as a modern center.
2. A Caribbean Hard Launch
The couple went public in May after sharing glimpses of a getaway to Turks and Caicos. Roberson posted a TikTok video of their matching outfits on the tropical trip, while Flagg shared photos on his Instagram story. This followed months of speculation, which intensified when she attended his NBA Rookie of the Year press conference.

3. An Elite Athletic Pedigree
Roberson's last name carries weight in NBA circles. She is the younger sister of Andre Roberson, the defensive specialist who spent seven seasons with the Oklahoma City Thunder. Both of her parents were All-Americans at New Mexico State University, and all seven siblings have competed at the collegiate level, including at Texas Tech, TCU, and West Virginia. It's a family tree rooted in hard work and high-level competition.
4. Texas High School Royalty
Roberson's transition to a Dallas-based partner should be seamless, given her legendary status at Clark High School in San Antonio. As a junior, she led her team to its first UIL 6A state championship. Her senior season averages of 18 points, 13 rebounds, and three blocks per game earned her a McDonald's All-American selection and the No. 17 national prospect ranking by ESPN.
5. Resilience on the Blue Devils Hardwood
Roberson and Flagg arrived at Duke for the 2024-2025 season with high expectations. While Flagg took the league by storm, Roberson missed her true freshman year due to a severe knee injury sustained at the FIBA 3x3 U18 World Cup. She mounted a remarkable comeback for the 2025-2026 season, anchoring Duke to ACC regular season and tournament championships and earning ACC All-Freshman Team honors. Her story is one of grit and determination.
As Roberson continues to develop at Duke, she represents a new generation of Latino athletes—rooted in Texas, connected to a global sport, and carrying a family legacy that spans generations.
