People need to get over this obsession with Dan Campbell. That type of HC is the exception in the league, and even then, he’s yet to have any playoff success. Most great HCs were still great coordinators who were able to develop leadership skills as well.
The fact that Campbell has won regular season games with a historically good OC (who is now gone) does not mean it’s not preferable to still pursue a HC with real Xs and Os skills on his resume.
It’s like arguing between taking a QB in the first or fourth round. Can you get a franchise QB in the fourth round? Yeah, but it’s the less likely path.
