PITTSBURGH -- The Steelers' fingerprints can be found all over the Green Bay Packers' playbook and game plans. Aaron Rodgers hears the Pittsburghese in Mike McCarthy's voice whenever he gets angry, and the Packers' postgame snack Sunday in their coach's hometown will be his favorite pizza. The Packers' coaching staff is loaded with Steelers alumni in defensive coordinator Dom Capers and assistants Kevin Greene, Darren Perry and Tom Clements. The Packers switched defenses from the 4-3 to the 3-4 because, well, it was the Pittsburgh way to go. "Their defense is one of the top defenses in the last two decades in the National Football League," McCarthy said.
