The Bears actually had several players put up very good performances, but they had far too many huge mistakes, especially on the defensive side of the ball.
The players don't deserve all the blame for the loss. The Bears were easily out-coached on both sides of the ball.
The Bears still scored plenty of points, despite playing the entire second half without starting quarterback Jay Cutler. Their game plan heading into the game was terribly flawed, as they basically ignored running back Matt Forte until Cutler was injured.
Defensively, the Bears gave up five passing plays of 20 or more yards to a team that had just 11 such plays entering the game. They were lost in coverage, beat at the line of scrimmage and appear to be the only team whose coach didn't study the read option in the offseason.
All of that said, the Bears still needed to play better. As good as their offense was at times, they had one huge mistake that resulted in a touchdown for the Redskins.
As the Bears enter their bye week, there are quite a few players who should be losing their starting jobs. You could argue one defensive starter in particular should have an even worse fate than that for his performance against the Redskins.
In the following slides, you'll see letter grades for many of the players on the Bears' roster. As always, I consider the expectations for each unit and the competition they were going against.
