I currently have hardy at ss. I basically hate him but i'm used to his cold streaks. Would it be worth it to trade any of the following sp's for furcal or S. Drew or hold tight with Hardy? Nolasco, Golardo, jobacum, kershaw, shields, zimmermann. I assume Zimmermann for sure but any of the others? The owners of Furcal and S. Drew said they'd deal them for a starter but I'm not sure Furcal or Drew is a big enough upgrade over Hardy.
If that's your whole staff, I don't think you have the arms to be trading one for Drew.
