Mavericks hire Mike Schmitz as GM, officially replacing Nico Harrison

The Dallas Mavericks are reportedly hiring Mike Schmitz as the franchise’s new General Manager, per Shams Charania. The team confirmed the hire Friday afternoon.

The move coincides with a front office overhaul in Dallas and follows Masai Ujiri being hired as the team’s new president in early May.

Following months of calls for his job, Harrison was fired in November 2025 after the Mavericks began the 2025-2026 season with a 3-8 record. Dallas has been conducting its GM search ever since.

Schmitz joined Portland’s front office in 2022 as the assistant GM. When the move was announced, it was speculated that his on taking over the Trail Blazers’ domestic and international scouting departments.
