It really is just not acceptable. I agree. For the record, the narrowest span over which the Mets had three postseason appearances is eight years: 1999, 2000, 2006. The narrowest span for four postseason appearances is fifteen years! (1986, 1988, 1999, 2000) There have been times when it looked like the Mets might be on the cusp of this kind of sustained success, like in early September of 2007. Starting with that collapse, the Phillies won, what, five straight division titles? That seems unthinkable that the Mets would ever do that, but it shouldn't be.
