We all know he won't be back, but we're paying him enough, I'd keep him around as long as I could. Let him scrub the locker room and don't give him a chance to get a new job elsewhere and help with any of their recruiting any time soon.
3-4 LBs are typically light and fast to the ball. 4-3 LBs are big and physical and not very fast laterally. We have probably the biggest LBs in the league. The secondary is another story and they just plain sucked.
