Safety isnt the biggest need on this defense...... go back and watch other great defensive teams and tell me what position on defense is the bigger need....
You care to tell anyone who knows football that Ed Reed isn't ht biggest part of the Baltimore Ravens' Defense?
You care to explain how Brian Dawkins isn't in the Top 3 important players for the Eagles Defense?
Wanna ask Mike Tomlin and Bill Cowher how much of an impact Troy Polumalu has on the #1 Defense in the NFL?
Wanna ask the Colts how important "Ex-Defensive Player of the Year" Bob Sanders is to them?
I would even venture so far as to say the Cardinals wouldn't be where they are without Adrian Wilson.
A Safety is asked to both stop the run AND defend the pass. If they are great at BOTH, how can you say this isn't arguably the most important position on the field?
