Steve Casula, who has been offensive coordinator at Ferris State the past two seasons, will join Jim Harbaugh's staff at Michigan as an offensive analyst.
Ferris State head coach Tony Annese confirmed the move in a text message to The Detroit News on Monday. It was first reported by Bruce Feldman of The Athletic.
Ferris State had one of the nation's top offenses in Division II this past season. The Bulldogs, who lost to Valdosta State, 49-47, in the national-championship game, finished ninth in the nation in total offense, averaging 491.4 yards per game. The Bulldogs were led by former Detroit Cass Tech quarterback Jayru Campbell, who threw for 27 touchdowns and rushed for 21.
Casula has a connection to Michigan offensive coordinator Josh Gattis; they both were on staff at Western Michigan in 2011.
Casula also has held coaching positions at Davenport, where he was interim head coach, Colgate and Delaware.
Earlier Monday, ESPN's Field Yates reported that Pat Perles, the son of former Michigan State coach George Perles, also will join Michigan's staff as an analyst/offensive line. Pat Perles, 55, has coached in the NFL and on the college level. His last listed job was as an offensive line coach at Syracuse in 2013. George Perles was the head coach at Michigan State from 1983-94.
Last month, two assistant coaches left Michigan to join rival Ohio State under new Buckeyes head coach Ryan Day.
Greg Mattison, who had been the defensive line coach at Michigan, is now OSU's co-defensive coordinator.
Al Washington left Michigan as linebackers coach for the same position with the Buckeyes. Washington’s father, Al Sr., was a linebacker at Ohio State.
