Looks like Quentin Groves is a free agent and he is probably not going to demand a very high price.
Here is his stat line from last year
Tackles: 46 - Nothing special, but it would put him around 7th in tackles for our team
Sacks: 4 - Nothing special, but it would make him our sack leader
He's got a little more experience. He's still pretty young and he could provide some depth at LB. He would also be an added threat as a pass rusher.
It's just a thought. Obviously we need to possibly target OT and CB first in free agency. Though we could still use some depth at LB and he would probably be fairly cheap.
