Since 2005, the combined efforts of the Miami Heat, Dolphins, and Marlins and the Florida Panthers have only amounted to a .494 winning percentage since 2005. That's the tenth worst out those 12 cities, with only Washington, D.C.'s .468 and Minnesota's Twin Cities' .463 being worse.
As it turns out, it's Boston, a city with fans who are notorious for feeling like they're constantly tortured, that actually fares the best. Its teams have a combined record of .611 over the past decade. Dallas is second with .577.
That data comes from the Washington Post, which has an excellent interactive infographic comparing all four-sport cities.
As it turns out, Miami also has the distinction of having the worst combined record for any four-sport town in all of history. Yes, 2007 in Miami sports wasn't just pure torture, it was historically terrible.
That was the year, of course, that the Miami Dolphins went 1-15. That was also the year that the Miami Heat began to fall apart after winning their first championship in 2006. The Marlins continued to Marlin and the Panthers continued to Panther, which is to say they remained completely mediocre. The teams managed a combined record of just .301. At least Miami managed to bounce back in 2008 with a combined record of .575, the best combined results the town has ever seen with all four sports.
As it turns out, the Marlins and the Panthers don't deserve the most blame. It's actually the Miami Dolphins that have sucked the most over the past 10 years. Here's each team's winning percentage since 2005, which — just for added torture — we'll show you next to Boston's results:
Things weren't always so bad. Miami became a four-sport town back in 1993, and the teams' total combined record over those years is .506. From 1995 until 2000, Miami teams managed to be above .500 every year.
