I went to my brother-in-laws house to watch them play the Vikes and Eagles. (Yes I watched the Skins games, too. He has 2 TV's in the living room.

In the Vikes game, the Bears were screwed by A LOT of bad calls. Their defense gave a up a few crucial touchdowns but were still able to come back and only lose by 5.
Keep in mind, their d was missing about 5 starters.
Against the Eagles, they started a new quarterback, Jonathan Quinn (who REALLY, REALLY sucks). The Bears were still plagued with bad calls but less than they dealt with aganst Minnesota. Chicago's D held them to field goals but their achilles heel was their QB. The receivers were open but he just couldn't give it to them. The Bears made several dumb mistakes but were still able to stay in the game against the 4-0 Eagles.
That being said, with Daniels on the roster, and Blache as our defensive coordinator, I think (hope) we will win.
I know our defense will do their job against Chicago's offense since Quinn is still QB. The only other main threat is Thomas Jones but he his production has gone down lately. But also look out for my boy and former Skin Bryan Johnson on Sunday. He has been an important part of their offense this season. Damn, it hurts to see him in another uniform besides the Redskins.
My main concern is how our struggling offense will fare against a defense that returns Brian Urlacher, who has missed the last 2 games, and Jerry Azumah, who not played a game this season.
I think that we are fit on ST and D but once again, our O, against a strong Bears D, will determine our success this week.
