Doesn't matter. Steelers have too much talent on Defense + they still have the defensive player of the year in Harrison.
Cutler is too erratic and doesn't have a great supporting cast like he did in Denver. If, Earl Bennett was his primary target again, then say goodnight to the bears.
Steelers will stop the bears only weapon and that is forte. Look at what they did to the two headed monster in Tennessee. Big Ben has too many options on offense
