I've lived in Pennsylvania and can tell you the fan base appears to be a lot like Nebraska. Much of their pride/ego/expectations is based largely on success that came many years ago (notwithstanding, of course, the recent run to the college football semi finals). But keep in mind they beat SMU and Boise State to get to the semis so a relatively easy path.
The good news for a coach at Penn State is you have 7 other sports teams between Pittsburgh and Philly to keep people busy complaining about other things. The bad news is that the media is insanely critical and so are the fans.
It sounds like Matt is adept at insulating himself from media noise. He couldn't care less (and probably doesn't even see) the vitrol on social media right now. His problem is going to be the donors.
The players, on the other hand, are going to have to deal with social media $hit at a different level. They've surely all seen it before, but probably not with this kind of intensity and frequency.
