Oh, true, not disagreeing with you on that.
But not all fans will continue to spend money on things if the team continues to lose, and even those that do will only spend as long as the team has some good seasons. For the last 20 plus years the team has had 10 or more win seasons followed by less than 10 wins. The up years give Dallas fans hope. But last year was 9-7, this year 10 or more wins is extremely unlikely. If the team follows 9-7 with like 6-10 or 5-11, I think you will see bandwagon fans start to drop away from supporting the team, which means buying t-shirts, hats, etc...
