It comes down to the fact that a vast number (majority?...not sure about that) of Alabama fans live all things current with Alabama THROUGH the glory years of Bear Bryant. It's not an attack on the man himself (although as any human, there was plenty to scoff at), but rather Alabama fans' inability to seperate those days and the feelings of entitlement they no longer garner.
Alabama is a LONG way from the those days, and the fact that in 2010, the memory of those days live on as a misguided expectation...of all things current....is ridiculous.
It is POSSIBLE Saban may very well lead Alabama back to those days, but I believe that even he has to wonder if he'd ever get his OWN legacy, or be placed in the same bucket with Bear even still.
I think we could probably guess how it would go.
