I'd have to assume that moving Marmol to the rotation would free us up to trade Marshall for an upgrade elsewhere. SS and RF seem most likely. Tejada, Marmol (SP), and Wuertz in a setup role, or Theriot, Marshall, and Marmol (RP). Obviously it would cost more than Marshall to get Tejada, but if we aren't giving up too much else, it seems very obvious which option is better for us.
