You have got to be kidding me! It's part of the essential job functions of an AD to be the face and voice of the University's Athletic Department. A skillful AD will utilize press conferences to put the Athletic Department in the best light possible. Press conferences afford an AD the opportunity to put favorable spins when things go wrong. They are also useful for great PR when things go right.
I only see ADs when there is a scandal or coaching change..the work is done behind the scenes
