As nice as it is if we were to sign LaRoche, I still think a key will be to maximize Morse's playing time. Whether it is at the expense of Roger B or Nyjer, the line up will look a lot better with Morse in left (or right, if Werth is in center). Morse hits righties well and does not need to be in a platoon (OK, he kills lefties, so if you had a righty killer I could see a platoon, but otherwise).
If the plan is to platoon Morse at first with LaRoche and to go with Bernie and Morgan in the OF against LHP, then I have real gas. Frankly, playing LaRoche at first and Morse in place of one of Roger / Nyjer makes me queasy too. This team may need a RHB for the bench in addition to Morse.
