I just listed a bunch of teams with new parks where that is not the case. The A's commitment to Billy ball means completely relying on winning to generate interest for revenue. The Giants didnt made the playoffs for seven years, a stretch where most teams would lose a ton of fan interest, even with a new stadium. But the Giants value having marketable players, even when the team is down, which keeps revenue up in down times because fans have attachments beyond wins and losses.
