at least one federal court has held that you can't get a refund on your season tix if your NFL team starts to perform crappily after announcement of a future move.
Fact that professional football team performed poorly after announcement of team's relocation could not serve as a basis from which to find that the team breached its contract with season ticket holders; to allow recovery under such a theory would enable any ticket holder not satisfied with the performance of whatever entertainment the ticket procured to seek a refund for such a subjective and unreasonable response.
