With Flagg shut down for the summer, Ryan Nembhard and other Mavericks players got extended on-court looks Monday.

Before looking too far ahead to Flagg's future, let's take a look back to assess his two summer league performances.

The opening day of the NBA Las Vegas Summer League provided fireworks and the debut of No. 1 overall pick Cooper Flagg, who struggled to find his shot in a dramatic win over the Los Angeles Lakers. Day 2 of the multi-week event from Sin City on Friday provided a further look into more prospects from last month's draft making their debut in summer league,

Cooper Flagg's first and likely only NBA Summer League is over. The Dallas Mavericks have shut down the No. 1 pick in this year's draft after two summer league games, according to a person who spoke Sunday to The Associated Press on condition of anonymity because the team had not revealed the move publicly.

It’s just one Summer League game, and Yang Hansen still has a long way to go to prove he can hang in an NBA rotation — let alone live up to the starry-eyed expectations of some Trail Blazers fans — but his Summer League debut went as well as could be hoped.

It’s not uncommon nor unexpected for teams to shut down top picks or NBA rotation players who are on summer rosters early.

Coward arrived on July 14 to Las Vegas to be with the Grizzlies for the remainder of summer league. The No. 11 overall pick in the 2025 NBA draft has "mixed feelings" about the decision, he said, but the Grizzlies decided that it was best for Coward to continue rehabbing his shoulder in Memphis before arriving to summer league.
