Serious question, what are the tasks day to day of an AD?
You would break it down into the management of internal and external functions.
Internal includes leading and managing the internal departments and their functions, which includes the team activities (all the coaches and the teams they coach), Athletics administration (all of the resources, equipment, uniforms, facilities management needed for the teams to practice and play), Sports Information (all of the communications to the external world, such as the website, press releases, interviews with press, etc.), Academic support (meetings with players, tutoring, monitoring of academic progress, helping student-athletes to schedule classes and graduate), "Development" (fund-raising efforts that support both operating activities and capital expenditure activities, and interaction with the Hurricane Club), Ticket Sales (both for home games and organizing the sale and distribution for away games), Strength and Conditioning (hiring personnel and maintaining the various workout areas and medical staff to deal with injuries).
External includes the oversight of contractual and other arrangements dealing with the scheduling of games and competitions, handling the interactions with the ACC conference, overseeing TV and radio broadcast relationships, particularly for games that are not picked up under the ACC contractual arrangements (secondary and tertiary arrangements that may involve lesser media outlets such as Sunshine, Sports Channel Florida, local radio, etc.), dealing with any shoe contracts, apparel contracts, merchandising and sales arrangements, handling our external facilities arrangements (particularly with Hard Rock Stadium).
Oh, and in case it wasn't obvious, working with UM on the budget, and occasionally giving interviews to the local and national press.
If I left anything out, I apologize and people are welcome to add on, but I think that is a pretty good starting point.
