While we all hope that Nolan, who's close to the root of that Ravens DC tree can work wonders, we can't expect him to be a magician turning water into wine. We've got some outstanding pieces in place including Starks, Merling, and Langford and high potential defenders in Wake, Smith and VD. Still Revis is in a class by himself, well, almost, and Jenkins, when healthy and conditioned, is a force to be reckoned with. Dansby would help, so would a McClain, but hell, I'd also consider trying Smith to FS if we thought we had a shot at Joe Haden, by all accounts a Revis clone. Additionally with a legit NT and coaching that either replaces players with those that better fit Nolan's optimal schemes, or transitionally, if he modifies some of his defenses to exploit existing players' strengths, we'd be well on our way to achieving Defensive parity on a position to position basis.
