On the surface, it seems laughable, but consider these elements: Swisher would give Kansas City a much-needed power source for the middle of their lineup, Romine has fallen behind Montero on the Yankee catching depth chart, and Posada's presence muddies the waters and hinders both players' growth, while Joba is from nearby Nebraska, and after the constant juggling of his role, he may welcome a change of scenery, which would come with a chance to start and be closer to his family. Kansas City would get three fairly cheap players capable of producing for them immediately in a competitive division, while moving a player who will become increasingly expensive in Greinke. That also hedges the Yankees' bet if Cliff Lee's wife really hates New York after her treatment by the fans during the ALCS. However, I don't know if Greinke has the right makeup for New York. Lest we forget, he did leave the game for a year to deal with personal problems. Assuming he is up to that task, a rotation of CC, Greinke, Pettitte, Hughes, and the unmovable AJ Burnett or Ivan Nova would be quite acceptable.
Lance Berkman showed that from the left side, he can still rake, but I think that he will look for a starting first base job elsewhere, creating a vacancy at DH. Replace the Big Puma with the Big Donkey. Adam Dunn's swing, when he connects, is tailor-made for Yankees Stadium. Moving Swisher would also open the door to signing Carl Crawford, and the Yankees would then have the fastest outfield in baseball, almost without doubt. A Rays fan that I know has said that Crawford seems to take days off, but I wonder if his attitude would change in front of 45,000 a night as opposed to 18,000 at the Trop. If the lineup plays out as Crawford, Jeter, Tex, A-Rod, Dunn, Cano, Posada/Montero, Granderson, and Gardenr, that would be formidable to say the least.
