Off the heels of an award-winning rookie season, Cooper Flagg has put his feet up on vacation and has seemingly hard-launched a relationship.
New pictures on Instagram showed the Mavericks star and Duke women’s basketball center Arianna Roberson having fun in the sun.
While the two did not share pictures of one another on Instagram, they both posted photos of themselves enjoying the same swings over the ocean at Noah’s Ark in Turks and Caicos on Friday.
Flagg, 19, sat in one of the swings while Roberson posed holding the swing and her sunglasses for her photo op.
The two seemingly met through their Duke connection.
Roberson overlapped with Flagg for a year at the school when they were freshmen in the 2024-25 season.
After Flagg’s impressive lone college season, where he won numerous accolades, including ACC Rookie of the Year, he declared for the NBA draft and was taken as the No. 1 pick by Dallas.
Roberson is no stranger to the game nor the demands of the pros.
Her brother is former NBA guard Andre Roberson, who spent six of his seven years in the league with the Thunder. His last NBA season was in the 2020-21 season with the Nets.
This past year as a redshirt freshman, Roberson averaged 8.0 points per game on 41 percent shooting across 33 games for the Blue Devils.
In his first professional season, Flagg averaged 21 points on 46 percent shooting. He also logged 6.7 rebounds, 4.5 assists and 1.2 steals throughout 70 starts.
The season culminated in him winning Rookie of the Year.
Flagg also joined Michael Jordan as the only rookies to lead their respective teams in points, rebounds, assists and steals since the latter was first logged in the 1973-74 season.
Despite Flagg’s early NBA stardom, Dallas missed the playoffs entirely.
It’s the second consecutive year the Mavericks missed the postseason since losing the NBA Finals in 2023-24.
