The offense hasn't scored 30 points in a game this season. Don't get me wrong; I'm not saying the offense hasn't been a colossal disappointment, but a not-insignificant part of that disappointment has to do with the defense not being able to stop anyone, ever. That puts a lot of pressure on the offense, and Cutler in particular, to be near perfect. Cutler's never going to be near perfect. That causes them to press, force plays, and make mistakes. It also doesn't help that, while the skill players are good, the line is not very good most of the time. Fix the defense=more possessions for the offense, more margin for error, less pressing by the QB who already has a problem with decision making at times.
