Anyone who watches the Packers realizes that CB Charles Woodson is used more as a linebacker or safety than a true Cornerback. However, with Williams being out, I could see the Packers deciding that they're better off with Woodson as a cover corner than Jarrett Bush.
In this scenario, two guys between Nick Collins, Morgan Burnett, and Charlie Peprah would account for both safety spots, and the other would be used in the box in Woodson's usual role. Luckily, I think Clay Matthews is in for a huge day against an inexperienced OT Byron Bell, so the pass rush should cover up some holes in the secondary. We'll see what the plan is soon, as we're less than an hour from Kickoff.
