I think players owe any program's fans and supporters hard work, a good attitude, and responsible behavior off the court. They're getting a free education out of the deal; they owe the fans (and if one wishes to further the point, the taxpayers) the best they can bring to the table.
If their best is not good enough, that's another matter. It's like my folks used to tell my siblings and I: "If a C is the best you can do in a particular subject, we'll be as proud of that C as we would be of an A in another class." But they did demand our best efforts, and they called us on the carpet when we delivered less than that.
I don't think anyone can argue that everyone on this squad is giving their all, on or off the court.
