NFL should be alarmed that three of four playoff games, including Green Bay's home game, still not sold out | Shutdown Corner - Yahoo Sports:
"It would be a tremendous embarrassment to the league to have three of four playoff games blacked out locally, and likely, the tickets will get sold somehow to avoid that scenario.

But there's a bigger issue here. Is this the most stark example that NFL fans aren't too excited to go to games anymore?
A quick glance at Ticketmaster on Wednesday afternoon showed the face-value prices for the Packers playoff game ranged from $313 and $102, not counting Ticketmaster fees.
If you've attended a NFL game, you know that the cost doesn't end with tickets. 
Parking is outrageously and insultingly high at most NFL games. 
Concessions aren't cheap either. NFL teams have gouged and gouged and gouged, and maybe there's a breaking point."
