The head coach is the man in charge. HCSF is the face of the program. I am never going to claim to be in a position to say this coach should go or that coach should go. I'm not qualified. I'm also not going to say (ok, maybe I do when I am pissed off) that this player or that player should go. I'm not qualified or not in the know as to how the backups are doing. For all we know, the "lack of culture" guys ARE the backups 
What I do know, however, is how the man should act when in a CEO-type position. He should be the shield in front of his team and his staff in public. He should be holding them accountable in any way he sees fit in private.
I don't think calling out players or lack of talent or even coaching should ever be done in public. Not because it isn't true, but because I don't think it helps accomplish anything positive. If someone is questioning players, plays, game plans, etc, he should be saying that it is his game plan, his approach and that players and coaches are doing what he is asking them to do. Because at the end of the day, it is true. He has picked his staff, his approach, his game plans and ultimately his players.
And if those players are making the same mistakes game after game, it is because he is allowing it to happen.
