Dallas Mavericks Reveal Roster For 2026 NBA Summer League, Including All Draft Picks

The Dallas Mavericks are less than a week away from the next stage of the offseason.

After adding four rookies to the roster last month, the Mavericks will have an opportunity to begin evaluating those players at the professional level when the team tips off action at the 2026 NBA Summer League in Las Vegas.

Dallas previously learned its schedule, which includes matchups against the Golden State Warriors, Los Angeles Lakers, Memphis Grizzlies, and Oklahoma City Thunder.

With the action in Sin City right around the corner, the Mavericks have revealed the 13 players that will be suiting up for the franchise in summer league.

All of Dallas' draft picks are included: forward Morez Johnson Jr., guard Sergio De Larrea, forward Tobi Lawal, and guard Vsevolod Ishchenko. There was some debate about whether Ishchenko and De Larrea would be able to join coming from Europe, but all signs point to them joining the Mavs, as De Larrea signed his four-year deal today.

Lawal and Ishchenko are more likely to earn two-way opportunities, depending on how they perform. The Mavericks are projected to have 13 players under contract for 2026-27, so there just might not be enough room on the main club, at least for now.

It'll be interesting to see how Ryan Nembhard operates as well, considering he has a year of NBA experience under his belt. Nembhard will be joining the team after wrapping up his obligations with Team Canada at the FIBA World Cup qualifiers.

The Mavericks do have another player on their summer league roster who has played in the NBA.

Guard Jaden Springer was drafted by the Philadelphia 76ers in the first round back in 2021. Philadelphia traded Springer to the Boston Celtics in 2024, where he won an NBA title as the Celtics took down the Mavericks in five games.

Springer ended up being dealt to the Houston Rockets the following season, where he was promptly waived. He also spent time with the Utah Jazz and New Orleans Pelicans.
