Well, since Brad Nelson likely won't land anything, I think I'd offer a reliever like Sarfate, the A's might value Nix's offense or Gwynn's game (as Beane has shifted to valuing defensive metrics), Zach Jackson, and another player of their choosing. Actually, Bill Hall makes some sense for them. Harden is a bit of a risk. He sprained his elbow ligament, so it's conceivable that he could finish tearing it in the next year or so. However, he's a player that is at least as good as Sheets, if not better, when healthy.
