I think Gov. Corbett knew, and was in fact building the case as AG when he was elected governor. Saw him say something like he had to bite his tongue b/c he had initiated the investigation and knew what was coming. But he clearly was not protecting Penn State, just painstakingly putting the case together
He also had made it public that he intended to attend the BOT meeting on Friday before it was moved up. Don't think his message was gonna be 'Hang in there, coach.'
Probably something more like "If you think Penn State is gonna continue to get millions upon millions from the state while allowing this situation to continue, you're sadly mistaken."
