re: Do you think we will ever have another D like 2011?

It's going to be tough. That defense was first in many categories. Moreover, they were first by a mile in several categories. To compare a defense to other all-time greats one would have to consider the era it played in. If memory serves the defense surrendered 13 touchdowns on the season. I think around 5 of those were returns. Something like 8. That is crazy good.

Note: I don't have the time now but I want to throw some stats down on this. I will do it tonight or tomorrow.
