True for sure - but the Ticket is for out of market customers, so I think you compare it to going to a season of games at the sports bar. I think the early sign-up discount was $349.
So for this year, the Saints appear to have just 3 national broadcast (primetime) games, so if you're not in the Saints TV market, you're looking at 14 games. Presuming you're the kind of fan (like everyone here) that wants to watch every game, that's just under $25 per game.
To watch at your house, with your store-bought food and beer, I think it's a pretty solid value. Yeah it's expensive and there are alternatives that require some tech savvy and may not be legal, but all things considered, it's the best option for being able to have the game at your house, on whatever TVs you want, etc.
