The simplest thing I can say about him is that he's average. Really average. I don't think he really hurt us at any point last year, but at the same time he never really made any plays aside from his first game here. I would say that if you're looking for a guy to hold down a position while you groom a young guy, then Witherspoon is a safe bet.
Sounds exactly like a guy the Titans would sign in free agency. Another thing to keep in mind is that Witherspoon isn't coming here to sit. If he signs that probably means the end of the road for both Keith Bulluck and David Thornton because more than likely Stephen Tulloch and Gerald McRath are 2/3 of the starting trio. I am not sure that Witherspoon is worth that.
