Giving this a bump for some more opinions. If I drop Lieber and with Nomo being shaky, it only leaves me with 3 solid SPs. The waiver wire is thin, but I could pick up a guy like Jose Acevedo or Ben Sheets. And if I drop Burnett, I'd surely lose him to someone who has room on the DL. So I guess my question boils down to this:
Considering my roster, can I afford to keep Walker when I'm deeper in offense than I am in starting pitching?
