Bo is a defensive minded coach. He doesn't know offense like the OC should, and he probably lays 99% of what the offense does on the OC. Can he nix the play call when the come in? Probably, but maybe he trusts in Watson to make the right decision. As a head coach, you need to not micromanage everything and let your coaches coach.
I really don't think Bo is much to blame for the offense's "suckiness" as much as a lot of people want to blame him. I will blame him for making a mistake if some personnel changes are not made over the offseason. Bo wants to manage the team on a day to day basis, coach up his defense to be the best damned D in the nation, and let his offensive coaches do what they do. He wasn't going to fire anyone during the season. Let's wait and see if any changes are made in the next few weeks.
If Bo spent more time righting the ship on offense, learning offense more thoroughly, I truly believe that the defense would suffer slightly, and that's something that I don't want to see happen. Offense wins games, defense wins more games, a good combination wins championships.
He can be blamed if he does not do something to fix the problem. He is not the defensive coordinator, he is HEAD Coach now. So he is responsible for the offense as much as he is any other aspect of the game. It is obvious that he isn't doing anything up to this point to fix the problems, and I really don't think Cotton or Watson have any idea what they need to do now.
This is exactly what i said. He can be blamed if he doesn't make a change.
Being a head coach doesn't mean you have to know both sides of the ball equally. That is hardly ever the case. The head coach's main responsibilities are to manage the coordinators and get the team ready and motivated for games. Not much more, not much less. He needs to hire someone that can take the reins of the offense while he falls into more of a manager's role. If Bo has an offensive strategy that he wants to go after, he needs to find a coordinator that is familiar with that offense, and spend the offseason setting the mold for the season. Once the season starts, he goes back into managing mode.
I'll compare this to the engineering field, since we are trying to engineer a solid football team. Bo is essentially the project manager. He spends his free time (offseason) teaching and discussing with his project engineers (asst. coaches) about the upcoming project (season). Once the project is underway, the project manager sits back, listens to feedback from his project engineers, makes recommendations, but by and large lets them do what they want. Once the finished project is put on the table, he can evaluate it and make the proper changes. The project manager doesn't necessarily know every bit and piece of the project, and is mainly concerned about the final product. Bo doesn't want to, or need to, micromanage the entire team. He needs to trust his coaches to do the right things on a day to day basis, and always be evaluating what they do, but not stepping on their toes.
Nebraska has a lot of young talent, and a lot of players that can lead Nebraska to the promised land. Bo now needs to evaluate the job done by his staff this past season and make the necessary changes, which in my mind, includes canning the offensive staff.
