Right now I see Greene, Meadows, Keith and Carp as your potential core players. The rest of the lineup should be open to upgrades if there are any potential ones out there. Don't pass on proven players for guys like Sweeney, Jung, Vierling and Tork.
If those guys end up improving/bouncing back great you can always find at bats for them but I'd like to get either more proven players or better players then depending on them next year.
