The Times has a lengthy profile of Graham Spanier, portraying the former-President of Penn State as very efficient, but very secretive. I had no personal interactions with Spanier during my time in Happy Valley, but I did spend an hour on his TV show last spring.
This profile jives with what I know about him. There was always this culture that Spanier was in charge, and from the central administration ran the school effectively, if not callously. I suppose this is what happens when someone has complete control of a city for 16-years. The story how the President and the Athletic Director (now under indictment) unsuccessfully tired to get Paterno to resign is symptomatic of how powerful the football program is, and makes the possibility of a cover-up more pronounced.
Interestingly, the web site for his show now redirects to the WPSU home page. Curious.
