The mistake they made was thinking they could make up the rotation on the fly year in and year out. Everything else has been whatever. To me, it's always been the rotation. Mookie, Xander, JD, Vaz, JBJ, Beni, et al left, but the Sox are still scoring runs. The problem is that the starting rotation is a steaming pile of horseshit because you need an actual plan in place and can't just pull a good rotation out of your ass.
