The Times has an article about the Mets Fan's Dilemma: who to root for in this year's World Series?
[T]he misery of this uninspired season has been unexpectedly heightened by the indignity of watching their most despised division rival face off against their despised crosstown rival in the World Series
For me, the question is simple: I've never rooted for the Yankees and I'm not about to start now. On the other hand, I can remember cheering on the Phillies when they were playing Atlanta (though it's funny how that has reversed). For all this talk of division rivalry, the Phillies are hardly the reason the Mets haven't been playing any meaningful baseball lately - the sad truth is that the Mets are their own worst division rival, three years running.
