Don Carey is currently fourth on the depth chart at safety for the Detroit Lions, but he's got several players looking to take his spot.
The top three spots at safety are basically locked in for the Detroit Lions. Glover Quin is the starting free safety, James Ihedigbo is the starting strong safety and Isa Abdul-Quddus is the top backup at the position. The Lions got extremely good play out of their safeties last year, and they have a lot of depth going into the 2015 season.
That excess of depth could potentially be bad news for Don Carey, who was the fourth safety (and occasional nickelback) in 2014.
