31. Kansas City Chiefs: Pass Rush
If all Chiefs opponents in 2008 had combined to make one football team, they would have been the least sacked team in NFL history, and all five lineman would have been in the pro bowl. That's just how good the Chiefs pass rush made their opponents look last year. They really didn't do anything to upgrade the pass rush; LB Mike Vrabel comes over from New England, which certainly won't hurt, but also doesn't bring a lot of upside to the overall production. The offseason focus on defense was about a move to a 3-4 unit, and bolstering the defensive line first and foremost. That's fine, but it still leaves them a step away from a competent defensive unit who can get after the passer at a significantly better rate than last year's debacle.
