Ben Johnson all day. I don't want another defensive minded HC. If the Bears are to hire an offensive minded HC then I hope they take a closer look at the variables on their resume.
Is Ben Johnson the mind behind the Lions offense? Yes. Is Ben Johnson responsible for the offensive game planning and in game play calling? Yes. Is Ben Johnson directly responsible for the further development of significant improvement of a now top tier QB? Yes.
Don't just hire another Nagy because of media hype and the assumption that he had anything to do with the Chiefs success. Anyonenwho really looked at that hire closely and was honest with themselves would have understood that Andy Reid ran the offense, came up with the game planning, called the plays, developed Mahomes in season and according to Mahomes himself it was working with JIM HARBAUGH in the offseason that also furthered his development.
Matt Nagy was a glorified coffee boy. Don't hire another coffee boy who road the coat tails of a HOF HC.
Then there was Trestman who I sometimes just think was a mean spirited practical joke hire. How any franchise would even dream up that hire is/was beyond me.
Add 3 new starting offensive linemen in the offseason and I think Ben Johnson would a field day with the core talent on the current offense.
