I mean, I am aware of maybe five or six serious, major athletic department cover-ups that went down while I was a student (one of them already being mentioned on this thread). Some of these were completely disposed of relatively quietly (the football gang-rape case, for example) and others resulted in jailtime and hefty fines.
On the other hand, there were some hilarious ones too. The Chas/Phonz rivalry/fistfight in study hall, the MRSA scare from the flooded locker room that was left un-fixed for three weeks, the janitorial staff catching boys in the girls locker room, the several facebook hazing scandals, the Ben Mauk cheating thing (very LOL), volleyball player peeing in the brand new whirlpool.
The one that really made me mad, however, resulted in the departure of a very talented and potential star football player in 2005. I forget his name, but he was either a cornerback or a wide reciever.
As most of my friends here know, I made a concerted effort never to reveal any insider information whilst I was a student. Some things are better left un-spread.
To put it simply, bad things that occur in the revenue sports are dealt with quietly and swiftly. Sometimes these things are no big deal (like Barclay's smoke-up outside of Groves) and sometimes they are something much more serious. The athletic department spends a whole lot of time and energy babysitting and regulating the basketball and football kids, and little effort paying attention to anybody else. They ignore the non-rev teams as long as they aren't getting in any trouble.
The extreme hate from one AD employee, in particular, against little transgressions in the non-rev sports was surprising and scary. I had friends that were hit with threats of yanked scholarship and being sent down from school for seemingly nothing, while there were rapes being covered up just across campus. Money talks, I guess.
