Donaldson has a chance to be a B+. He also has a chance to spend a hundred games unable to play in the field. Then what- Arreaz? Not sure he has the arm for the position, at least not as a long-term fill-in. Blankenhorn? Astudillo? If Donaldson stays reasonably healthy, we're in great shape. I think that for the division as a whole, catcher is stronger than 3B, but who knows. Grandal actually scares me more than Moncada, in part because he seems like that really solid veteran presence (and he's a much better fielder at his position, at least so far). Very worried about the Sox...
