I'm going to answer this as truthfully as possible. The Bears defense definitely has some weaknesses. However, most of their weaknesses take place between the 30's. Between the 30's, the Bears give up yardage. Their pass rush isn't what it should be these days. In the red zone, the Bears are still one of the best, if not the best, in the league. The Bears coughed up 4 turnovers in the first half, yet the defense gave up a mere 3 points off those turnovers. Stellar considering. Rex was horrible yesterday. I saw Kyle Orton play better than that, and Orton was horrible. To have as many weapons as Grossman has and play that miserably makes it even worse that he has such a bad day. He's got 4 respectable to excellent receivers in Moose, Berrian, Davis and Bradley. He's got a TE that can catch the ball. He's got running backs that found holes that should have opened up the passing game, but Rex just didn't have it. I was all in favor of letting Griese get some snaps yesterday. The Bears defense didn't allow the Vikings to score with good field position on many occasions. They were the better defense yesterday.
