Earlier in the season, some pundits were proclaiming Pittsburgh's proud defense to be slipping. One of those pundits was me, but I have since seen the error of my ways.
This defense wasn't slipping during their early season struggles as a 1-2 team; they were simply redefining themselves.
The Steelers' defense has built its sterling reputation off a fierce defense installed by legend Dick LeBeau, making its mark with aggressive play that results in sacks and forced turnovers.
This is far from the case in 2012, as Pittsburgh is 31st in takeaways and 24th in sacks this season, but they are succeeding all the same.
In their last four, the Steelers have allowed an average of 16.5 points per game, which would be third in the NFL if it were for the season.
While they aren't getting to the quarterback as often, they are playing great pass defense. They have allowed just 5.7 yards per pass on the season, which is good for third in the NFL, and over their last three, they have allowed just 5.0 yards per pass—easily the best mark of any team over their last three games.
They are also now second in the NFL in yards allowed per game. This defense is definitely still elite.
