I grew up in the South, but I have lived in PA for the last 12 years, and thus am exposed to the "Penn State Nation" (unfortunately my oldest boy loves the Nittany Lions, and thus I'm forced to watch them). While they like being in the Big Ten, they don't equate it to being the et all of college football the way a team that's been in a conference forever, and wouldn't be devasted is Penn State went elsewhere. Penn State fans just don't identify with the Big Ten as the other teams that have been there longer. Sorta the way Salsa and the Miami people feel about the ACC.
Even this comment board I happened upon agrees:

If I recall, Penn State wasn't doing all that great just before joining the Big 10, they played Ohio State and got beat, probably figured if they could join, they could play a better competitive schedule and win .... I really thought they thought they would waltz in the Big Ten and win every year.... that didn't happen.
