Because They Can Lie To You
And all the while commissioner Bud Selig beats his chest like an asthmatic, virgin King Kong for residing over "the most profitable era in the history of baseball." Nice. In addition to robbing the fans, Selig has also destroyed the game. Revenue sharing and the luxury tax have done little to level the playing field, and if anything, have made the competitive balance worse. Losing, small market teams have no incentive to win because they're bankrolled by the league's Goliaths to get their brains beat in. For those teams, investing in personnel is a bad business decision. As a result, the correlation between revenue and winning is more direct in baseball than in any other sport.
So, unless you're a fan of a major market team (or, rather miraculously, the Rays) you'll root for a perpetual loser. That loser will still charge you $40 for a ticket, $5.50 for a cold hot dog, and if you wear your Rockies hat to Dodger Stadium, you're liable to get pistol whipped in the parking lot. Rooting for the Blue Jays, Royals, or Mariners is hopeless. Those teams exist to cultivate prospects, turn them into stars, and then, hand them over to the Phillies or Yankees.
Last year Moneyball (a film about the 2002 Oakland Athletics) painted the team and general manager Billy Beane as the scrappy, creative anti-Yankees. The story gave hope to the notion that small market teams could compete as long as they were creative and willing enough to do so. In reality, the A’s won a division title behind three pitchers they were lucky enough to draft and a shortstop on steroids that won an MVP. A more fitting film for the current A’s would be Major League, a movie about a team trying to lose, kill off their fan base, and move to another city. It’s an example of the unjustified Hollywood romanticism that baseball is built on. It's all a fraud, really.
