It is not a necessity that Sandusky had anything on Joe Pa. Paterno had choice between turning Sandusky in or hiding the incidents. Paterno could simply have felt that if he turned Sandusky in that this type of conduct would reflect so badly on the entire program that the damage could be irreparable. as a result he chose to protect the brand rather than turn him in. He might have believed that Sandusky would stop the behavior once Paterno was aware of his behavior. Unfortunately the behavior continued and the situation got worse but by then it too late to do anything about it so the cover up just snow balled. We will never know
The problem with this type of thinking is, the cover up always ends up being worse than the original issue. To address it, it makes Penn State look bad for a little while, to cover it up STAINS the program for years (going on 4 1/2 now.)
Nixon and Watergate, Clinton with Lewinsky, the "offenses" were bad, but the deceit after the fact was always the bigger problem for me. Please don't turn this into a political discussion, I am only using these as examples.
I'm still shocked the apologists haven't "arrived" yet, they must really be busy fending off the "heathens" on other forums.
