Both horrific, but I'd say PSU because in the Baylor case the cover up was after the murder whereas w/ PSU their cover-up started after some abuses but by not doing anything to stop Sandusky it lead to many, many more instances of abuse.
Bliss is a real creep though - trying to frame Dennehy as a drug dealer after the kid was murdered was unreal. No surprise that he got fired as the AD and B-Ball coach at that prep school (why would you hire him in the first place is beyond me) for forging a signature to get a kid in school. It's in his DNA.
