NFL Feeling the Crunch?

It’s playoff time, but who can afford to go?  There are 4 games this weekend, and two of them were almost blacked out in the home TV markets.  Arizona and Minnesota had to get extensions to sell all their tickets.  Arizona eventually sold out, Minnesota is still trying.  Hmm, how could these games not sell out?  The Cardinals haven’t hosted a playoff game since way before I was born.  The Vikings aren’t exactly seeing the post season on a regular basis either.  Could it be that tickets are selling for $600 a seat and up?
