Yeah. I'm sure members of the Red Sox would much rather go play for the Marlins who are lucky to get 8,000 people on a weekday game, which turns into low revenues, which turns into poor players, which turns into losing. But I know that's far too convoluted for you to follow. I'll put it into simple terms for you. Fans = Revenues. Revenues = Good Players. Good Players = Winning.
But no, strong, loyal fan bases that stick around through s*****, losing seasons have no bearing on a teams success. You're right. The money pumped into the system is not at all tied to the fanbase.
