I think playing Pitt is a big deal. They are our one true rivalry since they are in state, most players and students went to school with each other...same with co-workers. Makes it a special week with lots of back-and-forth, bets, teasing. So its not just game day but all week, all off season, even all year. Makes it a lot of fun. Mich or Bucks just don't generate that same vibe.
As for the majority or not.....were you at the last Pitt came at the Beav? It was sold out, ticket resale prices were very high, there was a buzz and excitement much more than Illinois, Indy, N'western, or most Big 10 games, and at least 50,000 people were in the lots tailgating throughout the game. Looked to me like most PSU fans not only cared but were excited with the game
All that being said, I am in the school that says we should not play them anytime soon. Their program is very weak, they only sell half their tickets at home(without us, WVU, or ND on the schedule), and have struggled in recruiting. Playing them helps legitimize them, makes them money, helps their recruiting. Don't play them again until they earn it.
Sad to see it go as it is a fun time. But thats as it should be.
