What many people forget is the fact that a large number of schools have preferred and regular walk-ons. If the student athlete walks on, either preferred or otherwise and the coach decides that they want them, then the coach has the option to throw a little bit of extra money their way without it counting against their Athletic Scholarship moneys. Whether it counts against it the following year, I don't have the foggiest. But I was told this by several D1 and D2 coaches that want DD.
