As a rival, I've watched the Bears for about 50 years and that tends to be how they beat you. You make a mistake and they capitalize on it. If you don't do dumb stuff, you can beat them, if you do you lose.
That right there is why I have issues with this Bears regime. The Bears are usually a smart team that doesn't beat itself with stupid stuff like lining up offside or not knowing how to line up...they are not or don't appear to be a prepared football team
