On defense, five technique Cameron Heyward (son of former Bears fullback Greg “Ironhead” Heyward), linebackers Ryan Shazier and Bud DuPree and safety Sean Davis are the players the Bears have to focus on taking away.
First-round pick and younger brother of J.J., T.J. Watt (above), who was the star of the Steelers' Week 1 victory at Cleveland, will be out with a groin problem.
The Steelers have been rebuilding this group for several seasons, and at 2-0 they are eighth against the run, fourth against the pass, second in QB sack percentage and third in points allowed playing the shaky offenses of Cleveland and the Vikings without Sam Bradford.
Pittsburgh has only two takeaways in two games but has turned the ball over only once.
There is no question the Steelers are the better team here and worthy of being a touchdown favorite, but if quarterback Mike Glennon takes care of the football and the Bears' front seven can win the battle at the line of scrimmage, the Bears will have a chance to surprise.
