The idea of Jarret Johnson filling in for middle linebacker Ray Lewis Sunday is intriguing. Of course he's not Lewis, but to have a 270-pound inside linebacker is impressive. Johnson runs well and is relentless in pursuit. He'll only be used on running downs. Even with Johnson in the lineup, the Ravens still have a lot of speed on the outside with Bart Scott and Adalius Thomas, and I know defensive coordinator Rex Ryan will move Johnson around enough so he won't become a sitting target. With no Lewis and Mike Smith, the Ravens are making the best of a bad situation. The Ravens have a habit of drafting athletes who are good football players, and this might work out for them again in Johnson's case.
