I agree but it's also a lefty/righty thing. And neither of them are 1B level bats obviously. For now they are replacing Hall with Clemens and are surely going to play Bohm at 1B. If they don't do that, they need a RHB at 1B. If they want to move one of the corner OFs I think they should probably pick one, and do it regularly.
I think acquiring Pache was in part to protect Muzziotti. He has had a lot of bumps and interruptions and another cup of coffee is now that he needs know. I think they will just go with Sosa or Kingery or Guthrie if and when they give up on Pache. I think they knew exactly what they were getting when they got Pache, including the fact that he would probably go back on waivers (but might sneak through later).
