What happened: The Dallas Mavericks have set their summer league roster, folding in draft picks Morez Johnson Jr., Sergio De Larrea, Tobi Lawal and Vsevolod Ischenko. They join guards Ryan Nembhard and John Poulakidas on the squad, which will be coached by Joe Boylan.

Why it matters: Summer league is the first live look at Dallas' incoming class before the 2026-27 season, giving the front office a read on how Morez Johnson Jr. and De Larrea translate against pro competition. Reps here shape training-camp roles and the depth chart behind the veteran core.

What to watch: Watch how minutes are distributed across the draft picks once the summer league slate tips off, and which prospects earn expanded roles.
