Sagard is right, that only academically ineligible players who leave will lose you scholarships. So let's say you are a moron and can't hack it academically and are a member of the Square Root Club*, so you go to the USHL/Maj Juniors/a van down by the river. THEN your school is in trouble.
*The Square Root Club is for people whose GPAs are smaller than the square root of their GPAs. For example, if your GPA is 0.75, the square root of it would be .866.
