Hopefully the new AD will work with Harris instead of over Harris. We need these two lead horses to be in harmony. Reminds me of Ben Hur and the Chariot races where he had to balance the white Arabian stallions strengths and weaknesses to maximize their chances to win.
In short we need a competent confident AD not afraid to shown up by excelling subordinates, and yes, Harris by the way things are set up is not a truly co equal.
