Actually people here, to the extent that they are using a work analogy at all, are arguing that if your boss is ineffective, getting dress down by your boss' boss is not going to improve moral. But the work analogy is flawed. An effective team needs to have a collective, us against them mentality. Having AD say that the team performance isn't up to par and calling for an improvement is squarely part of his job. That conversation needs to happen with the coach, however. My expectation is that Manual undercut P's authority and lowered moral if he called out players. On the other hand, cheerleadery platitudes are normal for ADs, in my experience.
