The seats are empty when the bandwagon fans fall off. That's not a shot at the Yankees, the few good years with the Mets that I have experienced, winning always brings out bandwagoners. Especially in these new stadiums, the "real" baseball fan is gone. Speaking as a Mets fan again, the difference between Shea and Citi from a crowd standpoint is staggering. The baseball IQ, the knowledge of the team's history and their players, both former and current. The real fan was buried under the rubble of Shea and Yankee Stadium.
The real fans are at home watching. The bandwagoners are at the stadium.
