Black coaches filled more than half of the Division I men’s college basketball vacancies this offseason. Many credited a renewed effort for organized mentorship.

The Big Ten made the most impact. Penn State hired former Purdue assistant Micah Shrewsberry, 44. Indiana brought former Hoosiers player Mike Woodson, 63, from the NBA for his first college gig, hoping to replicate Michigan’s success after hiring alumnus Juwan Howard from an NBA assistant job. Ben Johnson, 40, a former Minnesota player and assistant and most recently a Xavier assistant, earned his first head coaching gig with his alma mater.
