I could use some thoughts/input on a trade idea.  NL only, keeper/auction league with contracts.  Other team has Holliday but also good outfield depth and possibly some open keeper slots.  His needs include pitching, CI, and possibly MI.  I'm weak in the OF, but have good pitching, and excess CI/MI depth.

Holliday ($9, 2 years left)
 for
Zach Duke ($7, 3 years left)
Mike Jacobs ($2, 4 years left)
Ronny Cedeno ($1, 4 years left)

  Is this a bad trade?  Is either side giving up too much?  What would be fair value for Holliday? I'd keep Holliday of course, but was planning on keeping Duke and Jacobs, maybe Cedeno also.  

  Thanks in advance for analysis and input!
