I really don't want Bienemy or Leftwich. Bienemy has some off-field stuff from the past and with either I'm not really sure how much of their team's success they are responsible for.
A defensive coach that brings a young offensive coordinator from a good offensive coaching tree would be interesting. But a lot of those guys are retreads like Todd Bowles or Raheem Morris. I wouldn't hate either hire depending on the staff they bring.
But to me, this is the perfect fit for Brian Daboll. He kinda looks like a guy Bears fans would love. Big, bald, meatball-ish. He has shown he can develop a run game. Shown he can develop a QB. He'd be a typical Bears hire, in that he's about as "safe" as a hire as they could get (so was Nagy), but one that might actually work out for a change.
The wildcard to me is Joe Brady. He had some interviews last year and a lot of teams probably felt he wasn't quite ready. But if Darnold is truly turned around and if Teddy Bridgewater keeps playing decently in Denver, his stock will rise a bunch. This is more of a high-risk, high-reward hire. And Brady strikes me as a guy that could be able to be involved in the GM hiring process should Pace go as well. He's the guy if you're swinging for the next Kyle Shanahan or Sean McVay.
