I've thought a lot about this, but I think Trestman has to stay as the coach of this team. There's just too much fluctuation when teams change coaches, playbooks, and potentially QBs. And there is so much value in HC-or-OC/QB stability. Brady/Belichick, Payton/Brees, McCarthy/Rodgers, Manning/Manning. It helps having a great QB, but Brees showed what can happen without your coach that orchestrated most of your success. I don't think the Bears are trading Cutler, so they are (for a lack of a better word) "stuck" with him. I think you stick with Trestman as the Bears are just 1 year removed from being a near offensive juggernaut, and Cutler is on pace to have his best year of his career, despite the turnovers being too high and points too low. I think you gotta stick with Cutler/Trestman combo and hope it all comes together next year (if it doesn't in the last 6 games) with a revamped defensive scheme. Of course, this is the Bears so they will just promote Pasqualoni instead of hiring a legit D coordinator.
