I have commented on this before, so I'll just say where I end up.
OC: Van Pelt might make a good QB coach for Maye, but he does not have the aptitude to be OC. If the replacement OC favors a scheme other than the one to which van Pelt is so doggedly committed, he could not serve even in the QB coach capacity. I would move on from him at season's end, and I might take play calling away immediately.
DC: Covington, I think, was simply not ready to take on the DC job. One day he might be, but the sloppiness of the defense's play and Covington's inability to adapt in-game to changing circumstances tell the tale. He has to go, again at season's end.
Mayo: To this point, his tenure is a failure: relationships among the team members and increasingly between coaches and players seem to be in a very bad place (pretty shocking for a HC who claimed to value culture and relationships), Mayo's in-game adjustments are either baffling or non-existent, and his messaging is preposterously inept (I would find such a guy very difficult to work for: he can barely get through a sentence without contradicting himself). He is just in over his head, I think. At this point I do not think his tenure is sustainable. I would in. fairness give him to season's end, but I really would not expect any improvement.
GM (or whatever they are calling him): Under both Bill and Mayo, Wolf's work has been abysmally bad. I would fire the preening nepo punk asap.
Krafts: The Krafts were foolish to perimit such a sloppy, cheap, unprofessional, slipshod hiring process for the post-Bill staff. Hiring an HC on the basis that the octogenarian owner found him a delightful travel companion is about the most asinine and negligent "hiring proces" one can imagine.
When it comes to the team management, we pretty much just have to start over. They can't pick the right players, and they can't effectively coach them once they are on board. Yikes.
