Mavericks forward Cooper Flagg sat out Monday night's Summer League game. The former Duke star and No. 1 overall pick is expected to miss the rest of Summer League, too.

Duke Just Picked Its Best NBA Summer League Player — And It’s Not Cooper Flagg originally appeared on Athlon Sports. 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.

The 19-year-old guard recorded a double-double (16 points, 10 rebounds) along with four assists, a block, and a steal in 6 minutes of action. He was the game's leading scorer right behind teammate KJ Simpson, who logged 18 points and seven assists. Both Flagg and Knueppel had standout freshmen seasons at Duke last year.
