I would probably rank them as follows, strongest to weakest:
Offensive line - thin at center, but otherwise pretty stocked if Schwartz plays well.
Linebacker - we have pro bowlers at three spots, so we're only down one and some depth.
Receivers - I'm going to be an optimist and assume that Baldwin and Avery play well.
Specialists - Good K, good P, someone can return kicks and cover, right?
Defensive backfield - Lots of CBs, a Berry who is hopefully recovered, and a weakness at FS
Offensive backfield - Charles alone should move this to the top, but he's the only strength we've got.
Defensive line - scares me to death.
