By the start of the 2014 season, with still free agency and another draft to go, we could have a depth chart like this:
LB: Mosley/Harris/Porter (Pace and Scott if resigned)
The one area not dealt with is Safety, other than resigning Bell and Landry. This I think would be of major focus for 2014 free agency and draft.
As of right now, the way salary cap and draft rankings/positions are as of today, this COULD be realistic.
