Eagles fired their OC Brian Johnson

The Titans, Chargers and Falcons are all going to be brand new staffs that will likely have 3 years minimum to show something. All 3 also have top 10 picks in this years draft. The Bears have the 1st and 9th picks in the draft and could turn things around quickly with a new OC and a few better players.

We have an underachieving team with an apparent leadership void, disgruntled players, a HC on the hot seat, an aging roster, bad cap situation and the 14th pick. I really don't think we're as attractive as some people think.
The Bears, as hard as it is to believe, are in a tough division. Detroit in Championship Game, Packers got really close and the Vikings are not that bad. NFC South looks like a cakewalk compared to that.

I also think that cost of living has to factor in a little bit for somebody like an Offensive Coordinator or position coach. New Orleans is WAY cheaper to live than Chicago, Atlanta, San Diego and Nashville. The only NFL cities that might be cheaper are Buffalo, Cincinnati, Detroit and Green Bay.

I don't think cost of living is a huge factor, but it might be for some people.

I've seen some estimates that coordinators make about $1 million per year.
