I like picking up Casey Urlacher as a safety to see what he can do.
As far as Colvin goes, I like him a ton, but right now I'd tag him and see what we can get on the trade market for him. I'd say we could get a first rounder and 3rd rounder of maybe even a 1st and 2nd and if we could do that it would be huge.
I like Colvin a ton, but he looks lost out their in coverage. Then renegotiate with Holdman, look to sign a veteran or draft a linebacker, and go with Knight, Howard, Urlacher, Holdman, Caldwell and another. Thats still a real deep core.
