For the same reason that everyone wants to throat punch Yankees fans who, when faced with current day reality, still yell out "27 championships" to prove how awesome their team supposedly is.
That ****'s in the past. Different era. Meaningless today. Others have covered this ... Paterno was simple, and his teams were simple, in a time when the game was simple. And there was tons of local talent to choose from.
There's a very good reason why PSU stopped being "elite," for the most part, during most of the last 2 decades of JoePa's reign. The game changed ... it got too hard for him. The talent moved elsewhere, as well.
I think, of course, everyone WANTS the program to be elite. The difference comes with one camp pointing to something 40-50 years ago, and acting like that reality should easily be today's reality ... and the other camp understanding that stuff has changed, and regaining that level of success in today's game, in the middle of nowhere Pennsylvania, is going to be a lightning in a bottle type of situation, and it's not worth getting upset about if it doesn't happen.
