The Dallas Mavericks have announced their Summer League plan for rookie Cooper Flagg, the No. 1 pick out of Duke University in this week’s 2025 NBA Draft.
Marc Stein of The Stein Line has revealed that Flagg does indeed intend to suit up in the Summer League next month — albeit briefly.
The early expectation is Flagg would play in Dallas’ first two summer league games: July 10 against the Lakers before San Antonio.

Dallas expects Flagg to play in each of the team’s first two Summer League matchups, on July 10 in a meeting with the Los Angeles Lakers and then on July 12 against No. 2 pick Dylan Harper and the San Antonio Spurs.
The Lakers only had one pick in this year’s draft, trading up from the No. 55 pick — twice — to select forward Adou Thiero out of Arkansas with the No. 36 pick. Second-year guard Bronny James, eldest son of 21-time All-Star Lakers forward LeBron, is slated to suit up for Summer League once again this year. The 6-foot-2 USC product spent much of his 2024-25 rookie season developing his game in the G League.
Dallas will wrap up its Vegas Summer League run with a July 14 matchup against the Charlotte Hornets and No. 4 pick Kon Knueppel — Flagg’s former Duke teammate — followed up by a July 16 meeting with the Philadelphia 76ers and No. 3 pick V.J. Edgecombe out of Baylor.

Flagg, considered the consensus top talent among this year’s class, could be a Day 1 contributor in Dallas. The 6-foot-9 forward averaged 19.2 points on .481/.385/.840 shooting splits, 7.5 rebounds, 4.2 assists, 1.4 steals and 1.4 blocks across 37 games for the 35-4 Blue Devils, en route to a Final Four berth. Flagg also racked up pretty much every significant NCAA award it was possible for him to earn.
A consensus All-American First Teamer, the 18-year-old was honored with a Wooden Award, a Naismith Award and the 2025 Associated Press Player of the Year Award. He was also named the 2025 ACC Player of the Year, as well as an ACC All-Defense honoree and NCAA All-Tourney
