You don't see Plouffe headlining a trade for a Derek Norris/Austin Hedges/Kevin Plawecki or similar catcher? That would solve the catching issue as well, and be a good haul for a good-but-not-great hitter in Plouffe.
I like where you are going with this. My dream is to sign someone like Jiminez and then figure out a trade for Homer Bailey (with resigning him) and the closer to spring training picking up a few guys on minor league deals to give a shot (like Kazmir last year) although I don't know who that is.
