Defense might not always win championships, but as the Seattle Seahawks proved last NFL season, it certainly helps.
With this idea in mind, we're going to spend the next 32 pages examining every NFL defense heading into the 2014 season.
Rankings will be based on each team's 2013 performance, roster turnover and front office makeup. Injuries and pending suspensions will also be considered in our analysis.
Defenses will be ranked based on projected performance, starting with the very worst and ending with next year's potential defensive juggernauts.
