GQ has a fairly lengthy excerpt of a new biography on Joe Paterno in their September issue. Currently, they're publishing part of it online and I found it interesting, if only because it shows some actual emotion from Paterno. Now, the emotion shared in this small excerpt is still emotion about Joe Paterno, but I can start to see where he may have realized the gravity of his inaction a decade earlier.
Here's the link. They have it broken into three paragraphs, and I'll blockquote one from the day following his firing below.
On Thursday, Paterno met with his coaches at his house. He sobbed uncontrollably. This was his bad day. Later, one of his former captains, Brandon Short, stopped by the house. When Brandon asked, "How are you doing, Coach?" Paterno answered, "I'm okay," but the last syllable was shaky, muffled by crying, and then he broke down and said, "I don't know what I'm going to do with myself." Nobody knew how to handle such emotion. Joe had always seemed invulnerable. On Thursday, though, he cried continually. "My name," he told Jay, "I have spent my whole life trying to make that name mean something. And now it's gone."
