From 1991 to 2006, 8 of the 14 champs asked their fans to pony up more than the rest of the league. So were the other six teams just being nice? Nope, in five of those six years the winning team had won recently, and increased prices, just years earlier. (That doesn’t include you, Philadelphia, so get ready.) But don’t think only winners pay a premium. The Chicago Cubs, 100 years since a title, have the second most expensive tickets. See where your team ranks. [Via Atlantic Economic Journal]
