Gordon/Rasmus is basically a wash at this point. I like Colby more but he doesn't get it done.
Joyce for Sandoval is heavily against you, despite your hopes on Sandoval's triumphant return.
Jurrjens for Marcum is heavily in your favor, K's being the major factor.
In total, the deal is fair, but you can do better. You aren't selling high enough on JJ and Joyce. I think you should, and this deal is close, I would just like to see Sandoval or Rasmus upgraded or combined into one much better player.
Goldy is King.
