Worst Sports Team Town

Okay, here's a good debate topic for all you sports fans out there.

My family and I have been discussing which is the worst town in sports. By "worst", we don't mean atmosphere or fan loyalty. We mean in terms of the overall performance of its major, professional teams in recent memory (say, the mid-80s and up).

The criteria:
1) The town must have at least two professional teams in the any of the four major sports (Baseball, Basketball, Hockey, Football).

2) These teams have to have been in the town for at least four years, so we can get a sense of how they're doing (so New Orleans wouldn't qualify, because it has only the Saints and the Hornets, and the Hornets have only been in N.O. for a few years [they've actually been there since 2002, but considering that they're also part time in Oklahoma City, I don't think they meet the standard]).

So, for example, has the aggregate performance of the Washington teams (Capitals, Wizards, and Redskins--the Nationals don't count because they just moved here) been worse than that of the Houston teams (Astros, Rockets, Texans)?

For what it's worth, my money's on Cleveland (Indians, Browns, Cavaliers). But Seattle (Mariners, Seahawks), Cincinatti (Reds, Bengals), Houston and Washington all are competitive.

Duke it out in comments.
