I feel like these last 4 games should be Trubisky's tryout. We're still technically contending. He played great against Dallas, and that's a great sign. He looked like the Trubisky that we thought we'd be getting this season. If he shits the bed in any of the next 3 games, or plays poorly, then we think about bringing in real competition for the QB1 spot next season.
That said, if he's expected to throw the ball 40+ times while we run the ball 12 times in any of these games, maybe we need to think about Nagy just focusing on being the head coach, and bring someone in to design the offense and call plays. Because Trubisky playing better the last several weeks is just as much about Trubisky as it is Nagy.
I hope we've seen some real change, and from here on out we'll be able to contend with Nagy and Trubisky. Fingers crossed, I guess.
