The person that I think this move has the most impact for is Plouffe. Think about it, Joe is at 1st, probably going to have Sano at 3b by mid summer. The outfield is going to be manned by Willingham, probably Hicks by some point in the summer, Arcia, possibly (very optimistically) Buxton at some point in the summer, not to mention any number of other options that might claim a spot like Parmalee, Colabello, Presley... I don't really see him as a DH. He is starting to look like a man without a position.
