The Dallas Mavericks tip off their 2025 NBA Summer League campaign tonight at 7:00 p.m. CT on ESPN in a must-watch matchup against the Los Angeles Lakers. All eyes will be on Cooper Flagg, the No. 1 overall pick, as he makes his highly anticipated debut in a Mavericks jersey.
Flagg enters the league with massive expectations after a standout season at Duke, and his debut is even more intriguing due to how the Mavs plan to use him. Head coach Jason Kidd has indicated that Flagg will spend time running the offense at point guard, testing his ball-handling, playmaking, and decision-making in an unorthodox role for a rookie forward. It’s a bold move that could accelerate his development—and provide fans with serious excitement.
Flagg won’t be the only young talent on the court. He’ll go head-to-head with Bronny James in what promises to be a high-profile rookie battle. The stakes and spotlight are only magnified. The game has already driven ticket prices sky-high, with resale prices among the most expensive in Summer League history.
Beyond Flagg, the Mavericks’ roster includes intriguing young pieces. Former Gonzaga guard Ryan Nembhard and sharpshooter Miles Kelly will be fighting for two-way deals. French wing Melvin Ajinça brings size and shooting, while 7’5” center Jamarion Sharp offers a rim-protecting presence that could turn heads. Former Texas A&M standout Zhuric Phelps also brings local interest and slashing ability.
NBA-experienced players like Maxwell Lewis and Jordan Hall provide veteran leadership to guide the younger prospects, while also trying to prove they belong on an NBA roster come fall.
Dallas will play four games in the preliminary round, with tonight’s contest being the first of a gauntlet that includes games against the Spurs, Hornets, and 76ers. A strong performance could catapult the Mavs into the Summer League playoffs.
Tonight’s opener is more than just a game—it’s the unofficial start of the Cooper Flagg era in Dallas. With high expectations, a national audience, and a marquee matchup, the stage is set for a memorable debut.
