I'd guess that there'd be confusion around what courses truly meet the NCAAs standards.
Say you take an Algebra and Geometry class Sophomore and Junior year. Then, your senior year you take a high school Finance class. Depending on your school's/state's requirements, that may be an acceptable math course to get your three math credits, but according to the NCAA that may not be sufficient.
If something like that was all that was holding up playing in college, I'd be selling pitchforks and torches while trying to raise a mob in Armory Square. But what I read was that he was 5 credits short. If that means that NCAA requirements were not met for 5 of his courses (and I may be completely wrong assuming that), who else do you have to blame but the student?
(Granted, I know there are extenuating circumstances where students do not always get the learning tools and support that they need in the classroom -- I typed this assuming that this was not one of those cases.)
