He's still a solid run defender and we need depth. Unless someone agrees to take on his starter money contract, which is possible, and offers at least a 3rd round pick or better, he stays.
This allows us to focus in on WR, CB, OT and OL/LB depth. If the real values are in the middle rounds as Buddy suggests, that could be good news for up and coming teams to take a step up by filling multiple holes. This draft also seems strong in our positions of need.
