This move tells me a few things (or things that IMO are at least likely).
1) Ryan Poles has had assurances from the higher ups that he is safe for at least a couple seasons.
2) Justin Fields’ chances of staying just improved. Fields is thought of more highly around the league than on HQ2 and Twitter.
3) Everyone thinks this means the Bears won’t get good OC candidates but I don’t think that’s true. As I said, Fields is more highly thought of around the league than he is by people on the Internet. Coaches are hired to be fired, they know this. They are nomads.
I think this job is plenty attractive enough because you have a defensive head coach and that makes the offense entirely yours. You’re about to get premium upgrades on offense, be they at QB or WR and probably on the OL. I don’t think you’ll have a problem finding good candidates, especially if you overpay a bit. Would be asinine if they didn’t overpay but it is the Bears so who knows.
Your floor for OC IMO would be Frank Reich, who would be a definite upgrade over Getsy.
