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.

That part of the team is important. It builds toughness. It builds strength. I've told it to many people in the last couple weeks that there are a few important rooms in the building, in any football building, and I think the strength and conditioning and the weight room is one of those important rooms.

I think the leader of that room is a very, very important figure in the organization, because those guys spend more time with the players than really anyone else does, if you think about it. They are always down there. If they aren't doing the lifting session they might be in there stretching. They might be in there getting a shake from the nutrition center. So, to have strong leadership in that position is very important to me.

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.
