​Michigan basketball has managed to retain the core of its roster despite the departure of coach Dusty May to the Dallas Mavericks, but the program’s coaching staff has still sustained a notable hit. Drew Williamson, who has spent the past two seasons as an assistant coach and recruiting coordinator for the Wolverines, has left Ann Arbor to join Dallas as an assistant coach. A source with knowledge of the situation, who spoke to the Free Press on condition of anonymity, confirmed Williamson’s move.
Earlier this summer, Williamson was selected to participate in the 2026 TopConnect Basketball Symposium, an exclusive leadership development event that brings together 50 rising coaches and athletics administrators. The invitation-only gathering is designed to cultivate leadership skills and strategic thinking among up-and-coming figures in the sport.
Williamson’s departure comes as another shakeup to Michigan’s coaching staff. Despite the turnover, he remains listed on the team’s staff directory as of July 9. However, a video circulating on social media before the Mavericks’ first Las Vegas Summer League game showed Williamson in Mavericks gear, actively involved in a drill sequence by throwing passes to Morez Johnson Jr., the Wolverines’ former big man and Dallas’s first-round pick in the recent draft.
This move marks the third staff departure from last year’s national championship team, signaling a broader transition within the program. Earlier, former U-M assistant Justin Joyner accepted the head coaching position at Oregon State soon after Michigan celebrated its title in Indianapolis in April.
With Williamson’s exit, interim coach Mike Boynton Jr. now faces the task of filling two coaching roles. In addition to Williamson, Mody Maor—who was brought in by May to replace Joyner—has also accepted a position with the Mavericks. Maor, 40, brings international coaching experience, having previously served as a head coach for the Nagasaki Velca in Japan’s B.League and as a coach for the New Zealand Breakers in Australia’s National Basketball League.
As for the potential future moves, it remains unclear whether additional Michigan staffers will follow May to the NBA. The program will likely evaluate opportunities for continuity and fresh perspectives as it navigates this transitional period.
