Thanks for the clarification, BC36. Regardless, I think the NCAA will hit them with more than their self-imposed penalties.
I would be very surprised if they didn't. If they go around letting schools dictating their own punishment, it would probably make the NCAA look bad.
This also explains why the universities give themselves less severe penalties. If the NCAA is going to hit them hard anyway, set your self imposed penalties a few notches below what you think the NCAA will so that they won't hand down a punishment tougher than what they would have said anyway.
Heard this argument on Common Man and the Torque one day; good points I think.
