It's always funny to watch non-STH talk about how they would behave differently, if only they were STH. As a prior STH, who has a long commute to the games, and not a lot of local Seahawks friends, I did have to sell many game tickets. It helpoed to offset the cost.
The Buffalo game was just as embarassing as the GB game, with the MVP chants getting louder and louder as the game progressed.
This refusal to renew concept is something that is being tried by several, if not all, teams in the NFL. I know GB is doing it. It will be interesting to see if it survives the inevitable legal challenge. The NFL's previous attempt to force a floor price on resold tickets failed miserably, which is why any other method of trying to control what is done with the tickets after a customer has bought them from the team, will also fail.
This is a novel way of instead refusing to renew the season tickets. I think the NFL has a leg to stand on, depending on what is in the contract that goes along with the purchase. I would think this will be impossible to enforce on those who hold licensed seats.
I might suggest that they publish criteria for what will be considered illegitimate levels of resale, but the true scalpers probably wouldn't care. They would just give away the minimum number of tickets per season, to someone who would attend. They wouldn't even need to go through one of the resell sites. It would be very hard to track.
Sure it would eat into their profit a little, but I don't think it would be very effective. In fact that is probably what will start happening here, even without published criteria.
