Who are the best defensive coordinators in the NFL today?
Much has been made about the constant flux of head coaches in the NFL. Due to the shrinking window of patience NFL teams allow their head coaches, defensive coordinators get even less time.
The longest tenured defensive coordinator in the NFL right now is Pittsburgh's Dick LeBeau, whose post began in 2004. The second longest is Mike Zimmer in Cincinnati who has been coaching up the Bengals defense since 2008.
A shocking 12 teams are starting 2013 with a different defensive coordinator then they had in 2012.
With these coaches only having a few years, if that, with a certain team, how are they supposed to distinguish themselves as sensational DCs?
For this list a collection of factors is considered to discover who is the best defensive coordinator in the NFL: Stats (How do the DC's defenses rank amongst the league?), experience (How long and how effective has the DC been in the NFL?), roster tools (does the DC benefit from great players or develop them?) and impact (What does this DC do that separates him from the rest?).
Also, any of the DCs that are entering their first season at the position in 2013 are automatically ranked last. They might end up being great, but without having coached, they don't deserve to be ranked ahead of experienced DCs.
So hold on to your seats, here are the best defensive coordinators in the NFL today.
