This sounds like an NCAA mandate to me...
The school does not HAVE to declare the individual ineligible. But if they do not, the hammer swings harder if the athlete is found to have been actually ineligible later by NCAA rules. The NCAA did not say that Cam was ineligible. They said violations had been found. To find out if those violations are enough to cause a penalty, then the school must follow the process.
But the NCAA prefers the institution declare eligibility and then they will rule on the validity.
So my statement stands, AU declared Cam ineligible, NOT the NCAA.
