The Detroit Lions have made some major changes when it comes to the team's strength and conditioning staff. Coordinator of physical development Jason Arapoff and assistant strength coach Ted Rath were among those fired, according to Dave Birkett of the Detroit Free Press.

Although general manager Bob Quinn did not confirm these firings, he spoke openly about the importance of a quality strength and conditioning department during an interview with Alex Marvez and Gil Brandt on Sirius XM NFL radio Wednesday night.

Via Lions senior writer Tim Twentyman:

Arapoff was with the Lions for 15 seasons, joining the team as a strength and conditioning coach in 2001. Rath had been in Detroit since 2009. After making the decision to keep head coach Jim Caldwell on board last week, this shakeup marks the first big move of Quinn's tenure as GM.

Quinn's decision to revamp Detroit's strength and conditioning department might be his way of changing the culture of the team at the most basic of levels.
