It's not common a home NFL team for a primetime game is an underdog. It's probably the result of that home team hosting a quality opponent while in something of a freefall themselves.
The Steelers (+2.5) host Chicago on Sunday Night Football in Week 3, taking their 0-2 Against The Spread record to Heinz Field.
Pittsburgh will be challenged by the Bears' new-look offense that features a much more refined and relaxed quarterback Jay Cutler. New coach Marc Trestman has done an outstanding job of keeping Cutler protected - both from Chicago's opponents and from himself - as they've started 2-0 with wins over Cincinnati and Minnesota.
While Cutler still has three interceptions, he's also thrown five touchdown passes, and amazingly, has only been sacked once. He'll challenge the Steelers' secondary, which could again be without cornerback Cortez Allen.
The Steelers might take solace in the fact home underdogs that started seasons 0-2 are 19-11 ATS since 2007. That's a bit obscure and doesn't lend well to blocking Julius Peppers, though.
