I think in this economy and with the sudden high, insurance costs people are just completely tapped out after the holidays. Who can afford $240 for playoff tickets.
A season ticket holder here in Seattle said he has rights to his seats, but he has to buy out the rest of the season. IOW, he buys all playoff games as if the team will play in the SB - then if they crap out he will get a refund. Pricey situation... Not sure about other teams.
