It's a double-edged sword.
If Coach Hud knew about it or tried to cover it up after the fact, then the university would be punished for sanctioning the rule-breaking or hindering the investigation.
If Coach Hud didn't know it (which I'm assuming right now that he didn't), then the NCAA could come back and claim that he should have known what his coaching staff was doing as official representatives of the program and claim "Lack of Institutional Control" which warrants punishment. This depends in what rules are in place at the universities and how the rules are enforced by the compliance officials at the school.
