BINGO! Right now, a lot of season ticket holders are selling their seats online at a huge loss and the people that buy them are obviously going.
Next year, the season tickets won't be bought, and the people that are buying the heavily discounted tickets this year aren't going to pay full price next year. Ticket prices will plunge, remaining season ticket holders will be pissed they paid so much for what is now selling for dirt, and the whole cycle will repeat itself the following year.
Owners whose only "assets" are a TV contract, season ticket holders, and some ad revenue, will see the value of all three drop substantially, while their liabilities (prima-donna contracts) remain constant. NFL team value plunges.
I’ve got PSL’s for the Texans, so I’ll be buying the seats again next year (otherwise, wasted the money for the PSL’s); however, just like this year, I’ll be selling every single game. Fortunately, not at a loss, but I didn’t try to make a ton of money either... just cover my cost, and maybe an extra $20-50 bucks.
