Jim Caldwell has a few remaining spots to fill on his staff including offensive coordinator, but it is starting to shape up.

Ron Prince was named the assistant head coach and tight ends coach on Saturday.

Prince and Caldwell worked together two years at Indianapolis (2010-2011) when Caldwell was head coach and Prince was the offensive line coach.

After the 2011 season the coaching staff was dismissed. Prince wen to the Jacksonville Jaguars as assistant offensive line coach in 2012 and spent last season as the offensive coordinator for Rutgers. He was also head coach at Kansas State (2006-2008).

Bobby Johnson, the Lions’ tight ends coach last season, has been kept on but will move over to be assistant offensive line coach.

Prince has specialized mostly as an offensive line coach. This will be his first experience with tight ends.

Johnson was the assistant offensive line coach for the Buffalo Bills in 2010-2011, his first two seasons coaching in the NFL.

One of the biggest hires has yet to happen — offensive coordinator. Until that person is hired it’s unlikely they will hire a wide receivers and quarterbacks coach.

On Friday it was announced, Caldwell is keeping eight coaches from Jim Schwartz’s staff.

Teryl Austin has been named defensive coordinator while NFL veteran coach Bill Sheridan, a Detroit native, has been hired to coach the linebackers.
