You can write off one scandal as an aberration. Two scandals signal a pattern. Three scandals mean you've got yourself a trend. Not the happy, pleasant or positive kind.
The Big Ten is dealing with its third sex scandal in a decade.

Ultimately, Sandusky went to prison, the late Joe Paterno lost his job and the program suffered a two-year setback that pales in comparison to the long-term harm done to the victims.
