We need to talk about this defense

It makes me jealous of the Steelers. They're consistently good on defense and allow their average offense a chance to win games week in and week out.

Our defense is jekyll and hyde. We don't know which defense will show up from week to week.
The Steelers have ran a 3-4 as their base since Joe Greene and L.C. Greenwood retired in 1982.
I've always liked the 3-4. You can blitz any of the 4 Lb'ers and still have 7 in coverage. The key
according to the late Sam Mills was having a NT who could take on double teams and not be
moved off his spot. He said NT Jim Wilkes was the real MVP of their defense. The Steelers just
have a knack for finding a good NT and those tweener DE/OLB types who can rush the passer.
