I don't think that is it at all. I would say the Jets are one of the least boring teams to watch. I think the crowd has a lot to do with age. Who are the wealthiest people in Winnipeg? Baby boomers. Small business owners. Medical professionals, most of which were born outside the country. 50 year olds don't generally make for a raucus crowd, I am sorry to say. Watch the old Jets and people were younger. They could afford to drink more beer, which makes for a louder crowd.
It's just economic reality. Look at the cost of a house, most have tripled and quadrupled in price in 20 years. That's real debt that people have to deal with, as well as ever increasing taxes and utilities. Job security is probably as tenuous as ever, especially government union jobs. And the Canadian economy could go into recession with Trudeau in power, which affects the operation of the team. One of the reasons I am not complaining that True North has gone the cheaper route this year, not unlike the old Atlanta days. but with better star power.
I started off with 5 games a year. $1000 investment. Now I just go to random games, through ticket sharing sites.
I think people know that it will take a community effort to keep the Jets, as the smallest market. Maybe the novelty will wear off. I don't see the next generation sustaining the team. So enjoy the ride.
