The structure of the Packers offensive coaching staff was a bonafide problem this season. It resembled a loosely bound committee with overlapping responsibilities and fuzzy assignments rather than a functional structure that clearly delineated roles, responsibilities and, especially, rank. McCarthy may be alleged to be a fine Xs and Os guy but he definitely failed this season as the coaching CEO. The offensive coaching structure should be recognized for what it had been for most of this last season: a disjointed failure. MM should be held duly accountable because he caused it and it is unquestionably his responsibility to now make it right. Denial is not a fix.
This is hardly a sentimental business. Coaches and players come and go regularly, and their ties to a particular team will always be tentative. MM needs to fix this organizational problem that he directly caused and move on. That may require that a little bit of housecleaning of his coaching staff. And if any coach's feathers got irreparably ruffled due to the peculiar organizational changes MM had made to his coaching infrastructure last off season (and adjustments subsequently made during the season) then those coaches will need to depart for the good of all concerned. If any of them have coaching staff buddies that are sure to pine for them should they be let go, then they may need to be let go, as well.
If MM follows this organizational debacle with an encore next season then it may be time for him to be let go, too. But that's a year away, minimum, if at all. That will be strictly up to him. This off season has the potential to seal his long-term fate one way or the other. It falls squarely on MM's broad shoulders. The status quo has proven to be undeserving of being maintained. Activities involving the coaching staff's (next) realignment will be interesting to follow during the upcoming weeks.
