My gut feeling is that Emery is probably 90% decided on who he's going to hire, but is going through the "due diligence" part of the process now. Emery is touted as being an extremely methodical and meticulous grinder, and we're seeing that play out in the coaching search. One good side benefit from grinding through this process, is that Emery is getting some exceptional input on the Bears from some of the brightest up-and-coming NFL coordinators - most of whom will be HC's sooner rather than later. I think some of these guys he's talking too are the "best and brightest" in the NFL.....just exceptional football minds. That's not the main purpose of the search, but rather a nice side benefit for Emery.
But I'll bet Emery knows right now who "The Guy" is. He'll pull the trigger when the process ends. We just have to wait it all out.
