It cannot be denied that, when the Steelers have been at their best in recent years—and throughout most of their history—it has been when their defense was the driving force. Now, that doesn’t mean that the offense doesn’t have to pitch in, but a top-five defense has been at the core of the majority of their Super Bowl runs.
Now for the first time in about a decade, give or take, they have that top-five defense again. They have All-Pros on all three levels of the defense, and a great supporting cast all around them. Depth might be thin or untested in certain areas, but they certainly have plenty of defensive linemen—and even cornerbacks, of all things.
