While many eyes are on Dallas Mavericks rookie forward Cooper Flagg amid the 2025 NBA Summer League in Las Vegas, he's not the only former Duke Blue Devils star attracting attention.

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.
