"The Cowboys are what we thought they were... if you want to crown their asses, then crown their asses!"
Grossman, in my opinion, had taken too much grief going into this season. A first year starter quarterbacks his team to the Super Bowl and everyone trashed him. But this year I cannot defend him. They have to bench him, I'd drop him to 3rd string behind Griese and Orton and hopefully for Rex's sake, with the pressure being taken off of him, he might be able to one day get another chance to get his career back on track. He's playing like a guy with ZERO confidence and at this rate will be out of football in no time, which is a shame because he has talent and potential, he's just playing awful right now.
As for "Romo riddled their defense with passing ease" as BottomsUp said, I'm not a Bears' fan per se, but I don't agree with your statement. Romo put up 3points in the first half, then the Bears D got tired from being on the field so long because of turnovers and quick 3 downs and punt series, and opponents are getting good field position as a result. Add the injury to Lance Briggs and Nathan Vasher (plus they're already without Mike Brown), and the defense just got worn down.
The Bears defense has given up just 10 points in the first half this season, but have surrendered 48 points in the second half when the defense becomes exhausted. Of the 180 minutes of game play so far, the Bears' offense has had the ball just 78½ minutes, that's putting the defense on the field for nearly 60% of the game.
There's nothing wrong with the Bears' D that some rest and fewer injuries won't cure.
