The line coach isn't the only one moving on from the Detroit Lions offense this winter.
The Lions have agreed to part ways with quarterbacks coach Brian Callahan, TheMMQB.com reported Monday. He'll be looking for a new job after two years of working with Matthew Stafford, and he's expected to have a fluid market to do so.
That means Detroit will have at least two vacancies to fill on the offensive coaching staff after it fired offensive line coach Ron Prince on the same day as Jim Caldwell's dismissal. It creates one more decision for Matt Patricia to make on his new destination, all while he tries to coach the New England Patriots defense to another Super Bowl victory.
