Drew Williamson Leaves Michigan for Dallas Mavericks

Michigan Keeps Most of Its roster After May’s Departure

Michigan basketball has managed to hold onto the bulk of its roster after coach Dusty May bolted to the Dallas Mavericks, a feat that rarely happens during a coaching transition. The program’s stability on the court contrasts sharply with the churn happening on the bench. As of Thursday, July 9, the team’s roster looked largely unchanged from the previous season. However, the loss of key staff members threatens that continuity. The departures signal a significant shift for a program that just won a national championship.

Williamson Joins Dallas as Assistant Coach

Assistant coach and recruiting coordinator Drew Williamson confirmed he is leaving the Wolverines to become an assistant with the Dallas Mavericks under Dusty May. The move marks his exit from a role he had held for the past two seasons. Williamson was invited earlier this summer to the 2026 TopConnect Basketball Symposium, an elite leadership event for emerging coaches. A social‑media clip captured him in Mavs gear, handing the ball to Morez Johnson Jr., Dallas’s first‑round pick.

Other Alumni of the National Championship Staff Exit

Williamson’s move brings the total of last year’s national championship staff members who have left to three. Former assistant Justin Joyner accepted the head‑coaching job at Oregon State shortly after Michigan’s loss in Indianapolis. Mody Maor, who May hired to replace Joyner, has also taken a role with Dallas. The rapid turnover leaves interim coach Mike Boynton Jr. with two open positions on his staff. Filling these spots will be critical as Michigan looks to maintain its competitive edge.

• Drew Williamson – assistant coach and recruiting coordinator, now with the Dallas Mavericks.
• Justin Joyner – former assistant, hired as head coach at Oregon State.
• Mody Maor – former assistant, joins Dallas after coaching in Japan and New Zealand.

Maor Brings International Experience to Dallas

Mody Maor, 40, brings a wealth of international coaching creds to the Mavericks. He previously led the Nagasaki Velca in Japan’s B. League and the New Zealand Breakers in Australia’s NBL. His background could influence Dallas’s approach to developing global talent. The hire underscores the Mavericks’ focus on diverse basketball perspectives. Maor’s arrival follows his brief stint as a Michigan staff member under May.

Uncertainty Remains for Michigan’s Bench

It is still unclear whether any other Michigan staffers will follow May to the NBA. The staff vacancies create a planning challenge for interim coach Mike Boynton Jr. as the program prepares for the upcoming season. The loss of experienced recruiters like Williamson may affect future recruiting pipelines. Michigan will need to act quickly to stabilize its coaching staff before the next recruiting cycle. The situation will likely dominate summer conversations among college basketball insiders.
