I appreciate the goal of having a policy...but when the NCAA doesn't require a written, department-wide policy, it's utterly foolish to use one. You can still have private, program-to-program policies wherein each coach sets down the rules and expectations and deals with it in his own way. Boeheim could have a different policy than Shafer, etc. That's what most schools actually do. That's what the school I work for does with athletes. But as soon as you announce you have a department drug policy, it comes under NCAA jurisdiction to make sure you're following it to the letter.
It's just idiotic on a number of levels.
