*The Ravens' secondary. This patchwork group has played so well lately that you sometimes forget that two of the best defenders (Fabian Washington and Lardarius Webb) are on injured reserve. When playing Peyton Manning, the Ravens will likely use their nickel package as their primary defense. That means Frank Walker could get over 40 snaps. Plus, Chris Carr has been pushed into a starting role after being the No. 4 cornerback at midseason. Can this group exceed expectations again?
