As a Nebraska fan, I get what Moranis is saying. After Osborne retired, the fan base demanded that Frank Solich be fired because nine or ten wins wasn't good enough. Then, after the Callahan disaster, they hired and fired Pelini, a good coach who led the team to division -- but not conference or national -- titles. Since then, the Huskers have been basically crap.
PSU is similar. Right now, they're at the top end of "B-list" teams. Sure, fans hope that replacing the coach vaults them to the A-list. More likely, the team regresses.
