Duchsherer to the rotation?

I know we all have been told that Justin is too valuable/too injury prone to be a starter.  But according to mlb trade rumors ( who heard it from Buster Olney (sorry not an insider so could not read what Olney actually said) the A's are considering moving Duke back to the rotation.  The merits of this idea are certainly debatable, but the more interesting aspect of a decision like this (if it is true) is that it almost certainly implies that Beane is thinking about moving a pitcher (or two) this offseason.  This could also be seen as an attempt at a backup plan for Harden as well.  

Just curious as to what everyone thinks this idea might mean regarding the future of Duke other A's players.
