Penn State was an anomalous situation, because they had a quasi-divine coach who had been there for 62 (!!) years, and who was basically allowed to run the place without effective oversight. It was an open secret that the AD, Paterno's nominal superior, was never hired without Paterno's approval. Can you imagine a job where you get to hire your own boss?
Because of that, I'm not really surprised that a scandal could be hidden there for a long time. No other college sports program is run that way, AFAIK.
If you click on a few of the imbedded links in the article...for example, one of the links takes you to the Miami scandal...the author isn't only referencing Penn State.
Penn State and Miami aren't the only scandals of late...Ohio State, etc.
I think Jim Lampley has a point (post #4)...What has become distinctive about some of the sports programs of late...especially football...is that it's now beyond an adjunct to the educational institution. It's now it's own entity, commercialized as such to suck as much $ from the region and nation as possible.
As such, more is tolerated within it because who wants to rock a boat hauling diamonds from the island where they it struck it rich with a diamond field?
