Outside Linebackers in a 3-4 are not always linebackers. Many are just undersized DE's currently we have Merriman (Showed up well when we re-signed him), Moats (Can't Cover, but can rush), M.Williams (Played well until his injury in Houston), K.Moore (Has not played there, but I can see him excelling at that OLB spot). Shep will be better inside with another guy like Barnett paired with him, and if not Nigel the beastman Bradham is ready.
Trade K. Williams and pick up an extra 2nd and 4th maybe. We are more set than you think we are.
