Cooper Flagg gave the Dallas Mavericks the offensive night they drafted him for, and then they took the ball out of his hands. The No. 1 overall pick scored 31 points in his second Summer League game, and shortly afterward Dallas announced it was shutting him down for the rest of the Las Vegas schedule, per ESPN.
The points came in a 76-69 loss to the San Antonio Spurs. Flagg played 31 minutes and finished 10-of-21 from the field, 3-of-9 from three and 8-of-13 at the line, adding four rebounds, an assist and a block. It was a firm answer to a quiet debut, delivered against Dylan Harper and a Spurs summer group with its own point to prove.
Why it matters
Two games was always close to the ceiling for how much a projected franchise player needs to show in July. Flagg addressed the one real question a wing his size carries into the pros — whether he can generate his own shot against NBA length — and the front office had no reason to keep him absorbing contact in games that do not count. The move is precautionary. Dallas has him slotted as the centerpiece of a roster that still expects Kyrie Irving back for 2026-27, and there is nothing to gain from a third and fourth exhibition.
The shutdown also quietly hands the rest of the Mavericks’ summer to their other rookie, ninth overall pick Morez Johnson Jr., who opened his own Las Vegas run with 27 points. For a front office that spent last season cleaning up after past decisions, watching both first-year players produce immediately is the kind of return that buys patience. The Middleton, Powell and Bagley contracts are off the books; the young talent is on the floor. That is the version of the plan Dallas needed to see.
For fantasy managers, the brief cameo only firms up Flagg’s redraft appeal. He profiles as a rookie who will get every opportunity to produce from opening night on a roster short on established scoring wings, with a multi-category ceiling across points, rebounds, steals and blocks that makes him a top-two-round dynasty asset. The shutdown carries no injury designation, so nothing about his availability entering camp changes.
