Basically guys you couldn't trade Andujar for without having some seriously good blackmail on the other GM.
If the Rockies could get Andujar, I don't think they would let oft-injured Danny Murphy be the obstacle. Did the Yankees let Ellsbury get in the way of acquiring Aaron Hicks?
Of course, trading Andujar for Schwarber, which is the thread title here, would just be a bad move by the Yankees...
