If we beat Cockeye, which we won't, Rhule needs to find a few scapegoats on his staff to cut. In my opinion, Satterfield is already on the way out due to his contract. So you have a chance to bring in a hybrid TE/OL coach who could help Donnie if Rhule decides to keep Don.
I could also see Dana moving on by his own accord as a mutual partings. But I feel that's less likely.
Defensive side is more tough to figure out.
Its really difficult to cut Butler after only being DC for one year. His scheme can work, but like Bo Pelini, his scheme works when everyone is top tier caliber talent at all levels. If your entire scheme relies on specific players hitting their specific assignment and making the play, then its not a good scheme for college football players.
So lets say Butler stays then. Williams, the DB coach, can stay. The DBs have been playing well regardless of a few key injuries. Year 2 will be his biggest determination.
LB coach? Honestly, hard to determine as well. For every time you think LBs play well, they don't the next drive or game. But they've been consistent. But not consistently saving us either. No one on the LB core has been a standout these last few years. They've been good, but not great.
Bradden, the DL coach. The DL this year has looked bad. No pass rush nor run defense. Seems like this group is the biggest WTF all season. But we also knew it was going to be a biggest WTF when Robinson and Polar Bear left. But how can you look at this group and not wonder, where did we go wrong the last few years to bring this horrible line this year? That can't be the first year coach's fault?
So that leaves Phil Snow. What does he do exactly? He came in as an advisor/associate head coach to help Rhule, but other than a few small things in terms of the general team's play, what has looked better? Nothing against Phil Snow, but this is your scapegoat for the defense side of things. He did his job that he was brought in for, but now its time to make a change here. This is where you need to bring in an experienced 'run defense coordinator' to help the DL and LB crew to stop the run game.
As far as NIL, focus on the lines for new talent. Especially a true NT and a DT or two.
