Mavericks Summer League Loss Raised A Frustrating Question About Their Young Guards

As the Dallas Mavericks stumble in the 2026 NBA Summer League against a weakened Lakers squad, questions arise about player readiness and future prospects.

The Mavericks’ 2026 NBA Summer League start has gone sideways fast, and Saturday’s loss to the Lakers only sharpened the concerns. Dallas fell to 0-2 after a game in which Los Angeles was missing first-round pick Cameron Carr, yet still looked more organized when it mattered. The Lakers also had just three players on the floor with NBA contracts - Adou Thiero, Chris Manon, and AK Okereke - while Dallas had six such players in Ryan Nembhard, Sergio De Larrea, John Poulakidas, Tobi Lawal, Tyler Smith, and Morez Johnson Jr., plus second-round pick Vsevolod Ishchenko.

The problem for Dallas wasn’t just the final result. The Mavericks got tangled up in the Lakers’ zone and managed only 26 points in the second half. That kind of offensive stall is hard to ignore, even in July.

Ryan Nembhard’s rough start is becoming impossible to overlook. He finished tied for the lowest plus/minus for the second straight game, and this time the box score was even less forgiving.

After opening against the Golden State Warriors with 15 points and 11 assists, he shot 6/15 from the field and 1/6 from three while finishing at -16. Against the Lakers, he put up 12 points, 5 assists, and 5 turnovers on 3/11 shooting, went perfect at the line, and ended at -22.

At this point, he doesn’t look ready for a primary rotation role next season.

Morez Johnson Jr. was the bright spot on the defensive end again. He blocked four shots and picked off two steals, following up a first game that featured five stocks.

His offense was quieter - 10 points on 4/8 shooting - but that’s not the part of his game that’s going to get him noticed first. Dallas could use more rhythm touches for him and Sergio De Larrea, though De Larrea hasn’t had a strong showing either.

Jaden Springer’s Summer League stint was another reminder of how far his stock has fallen. Once the 28th overall pick in the 2021 NBA Draft by the Philadelphia 76ers, then the G-League Finals MVP in 2023, and later enough of a prospect for the Boston Celtics to trade a second-round pick for him in 2024, he looked out of place here. He was repeatedly lost on defense, scored just 2 points, and the only other thing he logged was a turnover.

Mavericks Risk Wasting Their Best Chance To Fix A Growing Problem

The Mavericks still have real tools to address a roster issue that has been obvious for months, but the clock is ticking on whether they will actually use them. Dallas enters the next NBA season with a $20.8 million traded-player exception from the Anthony Davis deal and a non-taxpayer mid-level exception, a pair of mechanisms that could help reshape the back end of the roster if the front office chooses to act.

What makes the situation more pressing is the imbalance on the roster itself. The Mavericks are heavy on wings and short on reliable guard depth, a concern that only grows with Kyrie Irving coming off a torn ACL at 34. Dallas has already added Tarik Biberovic and Santi Aldama, but the bigger question is whether the team will lean on its exceptions or explore trades involving veterans such as Klay Thompson, Naji Marshall, P.J. Washington or Daniel Gafford to finally correct the fit. [Read more 🡒]

Mavericks Suddenly Pulled Into Wild Kyrie Move That Could Reshape Everything

The summer rumor mill has found a way to drag Dallas into one of the leagues loudest what-ifs, with Cleveland emerging as one of the reported finalists for LeBron James if he decides to make a return. From there, the chatter has spiraled into a speculative sign-and-trade framework that would tie together James Harden, Kyrie Irving, Miami and the Mavericks in one sprawling deal, the kind of construction that instantly turns heads because of the names involved more than any actual traction behind it.

For Dallas, the intrigue is less about whether this is close to happening and more about how quickly a hypothetical can reshape the conversation around the franchise. The reported setup is still just that, a framework and not an active negotiation, but it underscores how often the Mavericks get pulled into league-wide star movement whenever Irving is part of the discussion. Even without anything official on the table, the idea alone is enough to keep Dallas fans watching the dominoes around Cleveland and Miami. [Read more 🡒]

Lakers Just Made A Strange Luka-Connected Move Mavericks Fans Will Notice

The Lakers quietly cleaned up a batch of old roster paperwork this week, officially renouncing the free agent rights to Jared Dudley and a long list of other former players. For Dallas fans, Dudleys name still carries a familiar ring because he spent time on the Mavericks bench after retiring from playing, and his path through the league has kept him connected to some of the same circles that once overlapped with Luka Doncic in Dallas.

The move is mostly procedural at this point, since Dudley has been out of the playing ranks for years and has long since moved into coaching. Still, it formally severs the last contractual tie between him and the Lakers, which is the kind of transaction that barely registers around the league but can catch the eye when a former Mavericks assistant shows up in the fine print.
