To the question of whether this happens at all other schools in the country: of course it does. As to why ND seems to have so much crap poured on it by stuff like this, well consider two things:
1). WE are paying attention to every micro-element of every one of our players lives, and not anything like that for the other teams. Could it be THAT which explains why we notice our own guys' feet-of-clay more?;
2). ND has more people who hate us than any other school, this astoundingly includes many people claiming to be ND fans themselves [talk about psychiatric cases]. Whereas many universities can hardly find anyone who hates them enough to publish and continue to rag on them, people are trampling each other to sh!t on Notre Dame.
If [HAH! "IF"] WMU players were getting cheats done in class and sleeping with every woman with a pulse, do we think that anyone gives a sh!t? "Cover-ups" aren't even necessary. What is really surprising is that FSU, Miami, USC, never have this happen ... what? Wait...!
