I would not trade Melo for him, no chance. Zero. I would trade Palka, as I don't think he will hit enough, or field enough, to matter to this team (Buxton, Rosario, Kepler, Grossman, Wade, Granite, etc). I would be hesitant to trade Granite for him. I wouldn't trade anyone for him right now, as I don't think they are truly contenders still. If he's the third guy you pick up, after a legit SP and better RP? Sure.....Or if you are in first in July, sure.
