During a recent NBA Summer League game, the former Duke standouts greeted each other courtside before tipoff, sharing a quick handshake and smile. The wholesome exchange didn’t go unnoticed, especially by Flagg’s mom, Kelly, who responded to the clip on social media with a heartfelt message: “Brothers forever.”

Mavericks rookie Cooper Flagg has already turned heads in his first two NBA 2K26 Summer League games. The main takeaways from his early showings offer a glimpse into his potential and could help shape expectations for his fantasy basketball value in the 2025-26 season.

At Duke, Flagg averaged 19.2 points, 7.5 rebounds, and 4.2 assists and earned ACC Player of the Year honors while leading the Blue Devils to the Final Four. He also won the Wooden and Naismith Player of the Year awards and was an All-American.
