6. Kansas City Chiefs
Previous rank: No. 4
The Chiefs own a championship-caliber offense thanks mostly to their MVP quarterback. The question is, how is Kansas City going to get to the other guys’ quarterback? Alex Okafor aside, withJustin Houston departed and Dee Ford traded, pass rush must be coach Andy Reid’s No. 1 concern. Not to mention the potential patchwork awaiting new defensive coordinator Steve Spagnuolo. Spags made his name by leading a Giants defense that knocked off the top-seededCowboys and the Brett Favre Packers (at Lambeau) in the 2007 playoffs, and then finally the undefeated Patriots in Super Bowl XLII.
