Nakamura might be too sought after. I think a better fit for the Sox would be names that aren't appearing in rumors and such - someone along the lines of Kazuhiro Wada. Also, Kenji Johjima would look nice backing up Pierzynski. Couldn't be any worse than Ben Davis...
In case anyone wonders who the hell I'm talking about...
