Aaron Rodgers was on WSSP in Milwaukee and talked about how the Green Bay Packers prepare differently when facing the Bears. From Sports Radio Interviews:
The Bears are a common opponent so the preparation is a little bit different. I don’t think it’s less, it’s just a familiar team that we’ve played so I think that the film you watch, you have more to draw from. You know, Lovie [Smith] has been there as long as I’ve been there; same with Brian [Urlacher], same with Lance [Briggs]. You know, so there’s a lot of the guys I’ve played against now seven times, and so you watch film a little bit differently when you play these kind of opponents.
When the Packers went on their run at the end of the 2010 season, and into the Super Bowl, the offense was clicking, except in the two games against the Bears. As much as I expect the Bears offense to struggle against the Packers defense, the Packers offense is certainly going to have problems with the Bears defense. They just play them better than I expect, and I think that familiarity has a lot to do with it.
