PSU has been the leading football power in the Northeast for ages, but in terms of fan interest in watching their games, it faded as their national competitiveness declined and they moved to a midwestern league while the Big East raised the level of northeastern football. Of course interest in PSU football is still huge in Pennsylvania, but in New England where I live, you never hear them talked about and never see their games on at sports bars. There is more interest in Alabama than in PSU. I agree with your first point. We live in a what have you done for me lately society. PSU 2000-13 has not been The PSU of 1960-99. None of our supporters would claim otherwise. Unfortunately for PSU, Joe seemed to get old, complacent, and content with himself all overnight.
Suddenly a HC who always found a way to draft a winning game plan, and who was never outworked or out charmed by his rivals on the recruiting trail lost his fire. Meanwhile much of our conference was raising their games and gaining ground. This was a BAD combination. The result was 5 year stretch of football that we refer to as The Dark Years. In all fairness he did rebound a bit interspersing some conference titles, double digit win campaigns, and bowl victories into his last decade, but at his advanced age combined with the internal conflict on his staff between several assistants, it could not be sustained year to year any more.
To your second point again I agree. Joining The B1G was a shock to much of The Northeast and to PSU Fans in general. Thankfully our administration had the foresight to realize that they couldn't go it alone as an independent any longer. Amazingly The ACC had little interest in PSU, despite the fact that an invite would have likely been accepted. Sound familiar?
As to your last point I won't question you, as I spend little time in New England so I could never judge that for myself. I don't doubt that there is more interest in Bama than PSU in sports bars, as they are THE TEAM of the last 5-6 years and we are all fed a steady non ending diet of S-E-C, S-E-C, S-E-C, by the four letter. If Coach Franklin continues to recruit at the level that he has since his arrival, IMO we will be able to compete nationally again. It won't happen overnight, but in 3-4 years we will be able to compete for conference titles, and playoff spots. This could come sooner if further sanction relief is announced.
I think between James Franklin, the addition of Rutgers and Maryland to the B1G giving PSU more eastern exposure, and the demise of the Big East, PSU will come back somewhat in terms of northeastern fan interest. But Rutgers and Maryland may rise as well, since they are now on an equal footing, more or less, with PSU.
