They're scheming guys open and Mitch is missing them. I think the O line is fine, the defense is good, the offensive tools should be better, but the play calling and QB play are problematic.
That would be a mistake. That defense as built is pretty darn good and he didn't start with much. You just don't fire a GM when they build a team like last year's.
It's up to Pace to pull the plug on Trubisky early.
