This might not make you feel better about the state of your team, South Florida. Just know that lots of other folks elsewhere can commiserate and feel your pain.

There is one big problem with this authors methodology:   He does NOT take into account any franchises that have moved.  He only is dealing with franchises in their current location:

Examples:  The Football Cardinals,  Chicago/St. Louis/Arizona....have in fact gone longer than the Indians without a title....since 1947.  (though it is true that the Indians have gone the longest in their current city).  He also does not include the Sacramento/Kansas City/Cincinnati/Rochester Kings/Royals...who have not won since  1951. 

He says the Atlanta Hawks have never won a title....true...to a point.  The Hawks have won a title....in ST. Louis.

He ignores the Chargers entire history in San Diego. And he ignores the Washington Nationals history in Montreal, and the Rangers history in Washington DC.

So, while some of this guys information may be valid, a lot of it is bogus.
