I think that entire Detroit staff is solid. I like the playing experience too. Only question I'd have is how will his coordinators fare straight up vs some of the best in the playoffs. Will they give a little up schematically. But they have a unified message on what the team's identity is, and all that comes from Campbell.
Campbell's just a bit goofy. But all the best leaders have one thing in common and that's being themselves in that leadership position. Not trying to be someone else. Sounds really simple but you'd be surprised how many new leaders try to reinvent themselves in ways that don't work for them. Glenn mentions that too, which honestly just tells me it's a grounded group who at the very least have that shit locked down.
They have a lot of good pieces on the roster too. Offensive roster looks solid to me and they should be strong up front. The Parcells tree is one that I've always respected, because they tend to prioritize physicality which plays very well in the playoffs. Does identity match with their roster on offense... Yeah I think it does. Goff needs to make that big step as the leader of the group on the field and play well and it should come together.
Anyway I think that is one of the better first episodes I've seen of Hard Knocks. They probably don't have enough on defense this season but you have hard coaching going on and players with full buy in which are good signs for them.
