If they were at 95+% capacity this isn't a discussion. But they aren't. Last year they were close to 85%. And the real issue is the dwindling season ticket base. It's at ~10,000 people right now when it needs to be closer to 13,000. They reduced prices by 10-15% for season ticket packages and saw a gain of only 500 (~5% gain). By lowering those prices they may be bringing in less season ticket money this year. If the average ticket price was $100 last year and $90 this year they lose 50k of revenue per game compared to last year.
Plus, there is a massive difference in getting 5000 mores people in the building every night compared to 2000. Businesses plan most around guaranteed income and that isn't where it needs to be. Winnipeg as a locale also will have less corporate sponsorship which does put extra pressure on fans to fill the seats.
Yeah, but the Jets' owner has like $60+B so this difference wouldn't even be a noticeable rounding error.
If the Jets were owned by the Poor Sisters of the Downtrodden who were using the business profits to buy their daily macaroni & cheese these attendance figures might be a big deal, but such is not the case.
Also, for all the owners, the real profit is in franchise appreciation. Just look at Meruelo and that mess that he had in Phoenix with the Coyotes playing their last years in a college stadium with limited seating. At the end of the day, Meruelo paid $425M for the franchise and sold it for a cool $1B -- a profit of $575M.
