It's hard to say. College OC is not necessarily a direct route to NFL OC. After a few years as an NFL offensive assistant and one year as a college OC, QB coach on a team desperate for somebody to develop their star QB might be the best option to be a OC within a year or two, and possibly head coach even sooner. Unless he's getting a lot of calls from other teams for OC, this might be his best option. Well, I suppose he could see it as an inroad to a future OC job with the Bears if Lovie gets removed and Martz becomes the Head Coach or something.
