Calvin Magee, the offensive coordinator at Jacksonville State and a former Michigan assistant coach, has passed away after suffering a serious heart attack earlier this week. He was 59.

Jacksonville State head coach Rich Rodriguez released a statement on Friday.

“Our hearts are broken with the loss of our beloved friend Calvin Magee,” Rodriguez said. “Calvin was a great husband, great father and grandfather, great coach, great friend and great man. He impacted my life and the lives of so many others in such a positive way. Our thoughts and prayers are with his beautiful family – wife Rose, daughters Jade and Jasmine, son Bryson, his grandchildren, and all his friends and relatives. Our world is less, but heaven got better. I miss him dearly already. I love you my brother.”

Magee started his college coaching career in 1996 at USF. He was there through the 2000 season and then took a job at West Virginia as the running backs coach, a position he held until 2006.

In 2005, Magee was named the offensive coordinator for the Mountaineers, retaining his status as the running backs coach, as well. In 2007, he added associate head coach to his titles.

Magee followed Rich Rodriguez to Michigan in 2008, where he spent three seasons as the offensive coordinator and running backs coach.

Since his time in Ann Arbor, Magee has also had stops at Pitt, Arizona, New Mexico, Ole Miss, Duke and Jacksonville State.
