They are done
Pace has proven to be a bad evaluator of talent.
Nagy is NOT an offensive genius. He is a ridiculously bad play caller.
Trubisky is useless unless given the ability to use his full skill set which includes A LOT of running both designed and free lance scrambles. Even then he is just a little less useless.
The offensive line is substandard and it would be hard for any QBs or RBs to perform well behind it.
No Hicks clogging up the middle makes the defense surprisingly vulnerable to the run. The DBs have trouble covering if the pass rush isn't getting home.
Back to the drawing board
Replacements at GM, Head Coach and QB are probably needed unless some things change drastically very quickly. You would think after coming off of a bye that would have been this week if it ever was going to.
GB, MIN and DET are all much better right now and it isn't even debatable.
