Mavericks hire Mike Schmitz as GM, officially replacing Nico Harrison

The Dallas Mavericks have officially hired Mike Schmitz as their new General Manager, replacing Nico Harrison, who was fired in November 2025 after the team started the 2025-2026 season with a 3-8 record. Schmitz was most recently the assistant GM with the Portland Trail Blazers. The hire is part of a broader front office overhaul in Dallas, which also saw Masai Ujiri brought in as team president in early May 2026.
