Schultz's Super Bowl-week declaration, however, betrayed a civic truth most sports fans fail to acknowledge. If you think your hometown sports teams are all great buddies, you're wrong. The Celtics' biggest rivals aren't the Lakers; they're the Bruins. Paul Pierce and Kobe Bryant may compete for wins, but the Celtics and Bruins compete for money. There are a finite number of rich people in any given city, with a finite amount of money to spend on sports. When a team can make the same amount of money selling two courtside seats as they can selling an entire section of the upper bowl, they'll target their sales strategies accordingly. Getting the affluent to your games means pampering them the minute they walk through the doors.Maybe Repanich is right, maybe he's just another bitter and betrayed sports fan. But the idea that the stadium arms race is fueled in part by professional jealousy among team owners fighting for the limited, desirable customer base -- "desirable" meaning very rich -- is a compelling one. Is that hard to picture Stan Kroenke visiting downtown and being jealous of that massive new stadium that isn't his? Whatever is in those top-secret proposals and counter-proposals between the team and the CVC, you can bet that most of the desired changes to the stadium will cater to people who meet that "desirable" criteria.
