Earlier this summer, ESPN's Buster Olney reported that Major League Baseball and the players' association had recently discussed a form of realignment that would result in two leagues of 15 teams, rather than the current structure of 14 teams in the American League, and 16 in the National League. This sent the sports world into a tizzy as baseball geeks everywhere weighed in on how best to realign MLB. There are a lot of ideas out there: shorten the season so each team gets one day off a week (said to be a favored position of Commissioner Bud Selig), move the Houston Astros or Florida Marlins to the American League; create three divisions of five teams each; do away with the divisions entirely; add an extra wild-card team to expand the playoffs.
There's also a discussion about finding ways to address the disparity in miles traveled. According to this neat interactive graphic put together by Paul Robbins at the New York Times, in 2009, the Dodgers traveled a league-high 59,742 miles, while the Nationals traveled less than half that, 26,266 miles.
Not to be left out, we decided it was a good time to convene a Freakonomics Quorum. We rounded up a handful of sports economists and asked them the following question:
What proposed realignment changes seem to make the most sense from a competitive and economic standpoint for Major League Baseball?
