According to a source I used, the Bears organization has the 5th highest average ticket price in the NFL. Of the top 10 teams in cost, six made the playoffs. Of the top 15, nine made the playoffs. Seattle was 11th and New England was 12th. Other sources quote different placement. But, I would expect the ticked prices for the Bears to go up exponentially when the new house is opened.
If you look at ticket prices as a Chicago thing here is what I found. The Bulls have the 7th highest average ticket prices in the NBA. The Blackhawks have the 3rd highest average ticket prices in the NHL. The Cubs have the 4th highest average ticket prices and the White Sox came in at 26th. Again, not all sources have the placement the same. But all are pretty close.
Outside of the Bears, it's a lot of money to watch very average to bad teams.
