PSLs are as good as stocks when the team is winning. In some future date, when you sell your seats, you will recoup the PSL from that buyer plus a premium.
The modern NFL charges these everywhere including in the other blue collar towns. I think people forget that a season ticket for the Sabres 100 level is $8000+ per ticket so when the cheaper PSLs $s come out around or lower than that, it’s relatively cheap.
