I think the mathematical analysis of this signing for the Yankees doesn't really tell the whole story at all. "Star power" trades at a premium for them because they have an image to uphold with their fans.
I do think that this is a terrible deal for baseball. Nobody wants to see the Red Sox/Yankees rivalry diluted like this. Every baseball fan is going to hate this. To take one of the great personalities of the game (who was part of one of the great stories in baseball history) and have him turn into a hired gun is very sad.
