Here is the problem. The NCAA has specific rules and they have Lack of Institutional Control rule. One part of LOC is that athletic department members most follow all institutional athletic department policies. If they fail to follow them it is an NCAA violation. So if Rutgers policy is a coach may not contact a professor directly then it would be an NCAA violation for the coach to contact directly.
As far as the NCAA it not a big deal to the institution, however the impact to Flood could be bad. By that I mean Rutgers will not lose scholarships or post season ban. However for Flood he could face a show cause penalty which gives the university no choice but to terminate him. The violation is black and white (If contacting a professor directly is against RU rules). The severity is a whole lot of grey. Does the investigation committee feel like it was an attempt to get an improper benefit? I think it looks bad that it from his personal email because to many that would show an intent to conceal. No one right knows. He may just need to take learning course and probation or he could face suspension.
So are you saying that abusing children wasn't in PSU's code of conduct, so they never took any disciplinary action because it wouldn't have resulted in a lack of institutional control?
