I've mentioned before in this blog that the system of promotion & relegation in European league sports is the "awesome Shiva of sports, destroyer and transformer." US sports leagues are worse for not having promotion & relegation; however, even with 24/7 coverage of sports in this country, most sports fans have no idea what promotion & relegation are and how they'd change their favorite sports.
O Dear MLB Fan, if your sport had promotion & relegation like the European soccer leagues, the bottom three teams in the MLB would move down to the AAA league, and the top three teams in AAA would move up to the majors. The end of the season wouldn't merely mark a battle for the wild card spot: It'd be a life-and-death battle to stay in the MLB and we'd all be glued to our televisions.
If the baseball season ended today, and MLB/AAA promotion & relegation operated the same way it does in the English Premier League, the Nashville Sounds (89W/55L, .618) of the Pacific Coast League and the Scranton/Wilkes-Barre Yankees (84W/59L, .587) of the International League would be promoted to the MLB. Playing a 4-team mini-tournament for the final slot would be Sacramento River Cats (.583), the Toledo Mud Hens (.573), the Durham Bulls (.599), and the Iowa Cubs (.549).
As it currently stands, 6 MLB teams – the Chicago White Sox (.433), the Kansas City Royals (.433), the Pittsburgh Pirates (.427), the Baltimore Orioles (.427), the Florida Marlins (.427), and the Tampa Bay Devil Rays (.414) – are seriously at risk of finishing in the bottom 3 slots for the year. Relative to other teams in the league, these teams are horrible. And because we have a system where they're locked into the top flight professional baseball league, they can get away with being horrible.
Under a system without promotion & relegation, the players for these teams will simply go through the motions for the rest of the season, playing their remaining games lackadaisically. The best of these teams, the White Sox and the Royals, are 25.5 games out of playoff contention: What do they care who wins or loses the remaining games?
Under a system with promotion & relegation, these players would be playing like madmen. Presently, sportswriters are shocked when teams that have had a rough season play their best at the end of the season. If we had promotion & relegation, this would be commonplace, as each threatened team battled to stay in the top league.
Owners would be forced to invest in their teams or risk falling out of the league — you wouldn't see them employing a penny-pinching strategy of running a wildly profitable but unsuccessful team (See Bud Selig or (outside of baseball) the Golden State Warriors).
What do we get instead of relegation & promotion? We get a Congressionally-sanctioned monopoly for major league baseball. We get meaningful games at the end of the season only for those teams at the top. We get a farm system where the teams are locked into their divisions and financially dependent on their big-league paymasters. We get less.
7 of the Chicago White Sox's final 14 games this season are against the Kansas City Royals. The team that wins the majority of these games will move up the table. The team that loses the majority will probably end the season in the bottom three teams.
Without promotion & relegation, you don't care about these games and nobody else does, either.
With promotion & relegation, you'd care, the players would care, the owners would care, and you can rest assured that the people of Chicago and Kansas City would care.
