Defensive Free Agents: Shopping List

I would like us to go after Corey Williams, Lance Briggs as our top Free agents.

Then look at Madeiu Williams, Eric Coleman, Gary Baxter, Demorio Williams, Chaun Thompson, Teddy Lehman.

I think any of the above can compete and most probable replace one of our present defensive starters, which would open up our options in the draft a bit more.
