I voted Corey Williams because I think that a better pass rush will improve the entire defense, while Lance Briggs may not be as affective without guys like Brian Urlacher and Tommie Harris around him.
I would respectfully disagree with this. I believe that the draft is stronger with linebackers who can come in an contribute right away as rookies. Rookie CBs, even the great ones need a season or two to develop in the NFL, with a few exceptions. I would prefer a veteran CB, and draft LB high.
