Based on persistent threads on this site and others, there is still anger, meaning there's still passion for the team. Which means that should they get randomly lucky wth a decent team as they did a couple years back, people would still respond.
If there were no threads, no posts, no anger expressed, that's when they should worry. That indicates everyone has completely checked out.
It's something Pitt has to keep an eye on too. Like this board. Other than OT and Locker room, actual football and basketball traffic appears diminishing, similar to attendance. A second straight week playing a good team where we're generally predicted to get slaughtered, yet there isn't particularly much being discussed, not even disgust (one time UCF posters don't count)
