Michigan dropped the interim tag from Mike Boynton Jr.’s title and has agreed to a two-year deal with the former Oklahoma State coach, it said Friday.Boynton was named the interim coach after Dusty May was hired as the Dallas Mavericks’ new coach. Boynton told The Athletic in late June that he was going through the interview process to have the interim tag removed and become the full-time head coach.The 44-year-old has spent the last two seasons as an assistant at Michigan, helping run a defense that ranked No. 12 and No. 1 in adjusted defensive efficiency at KenPom over May’s two seasons in Ann Arbor. Boynton also had a top-20 defense in three of his final four seasons at Oklahoma State, and he told The Athletic that he plans to continue to run the defense and hire an offensive-minded assistant to run the offense.“Mike is a veteran assistant with strong head-coaching experience and a clear understanding of the standard we expect at Michigan,” Michigan athletic director Warde Manuel said in a statement. “Over the past two seasons, he has been an invaluable member of our staff, bringing stability, leadership and perspective during an important period of success. Our players and staff believe in his vision, are committed to his leadership and are excited for the opportunity to pursue great success together this season.”
