I'll weigh in on this as a season ticket holder for 33 years.
I'm on the fence about renewing due to the recent events, not just the cheap shots at Belichick, but decisions made about the stadium, team and general good will to the fans. My wife has convinced me to renew for one more season, but my patience will be very thin.
Start with Kraft sinking $250 Million into something that will always be underused. For those who may not know, that new club he built requires STM's to not only purchase their regular seats, but also purchase the right to use that club, more than doubling the price if you choose to be allowed into it. For 2 tickets, it's not like you can now have 4 bodies in the stadium, it's 2 bodies for 4 spots, I can't be in two places at one time. It's insane to think that the average Joe Schmuck like me will pay double for two sets of seats when I can only use one at a time. There were not a lot of people using that facility this past season. That's just an example of his contempt for the paying fans. And, of course, the concessions are high priced and the food is not worth half the price (I rarely get anything in the stadium). And it shows when visiting fans are slowly taking over the stadium, something that has not happened since the Rust and MacPherson days.
They must be worried. I've received multiple calls from the ticket office since last October when I never heard from them in the previous 32 years. They offered me a couple of nice game time free perks last year (we got to go on the field post-game after the Washington game, got to go up to the top of the lighthouse during the Chiefs game) and got a call out of the blue 2 weeks ago just to see how I'm doing (the invoice arrived 1 week later). The alarm bells are going off in the ticket office, but I doubt the Krafts are hearing them. I've heard that advertising revenue is down and the renewal rate is expected to be not close to what it's been in the past 20 years.
For me, I not as young as I used to be and for me to put out a decent sum of money along with the effort it takes to spend a day in Foxboro, I need to know that there's a plan that makes sense, that give me a reason to renew that investment of money and time. If I don't get that by the end of next season, I'll be happy to sit in front of the TV and use that money to go on a nice vacation. We'll see......
