Maybe it's me, but why can't you move Stanton straight up for McCutchen?
It's not that far off, and if the other guy gets 2 more years of Stanton (as he's hitting his prime) and if the other guy needs a McCutchen replacement, a 1-for-1 makes a lot of sense...
Then, maybe try to package Gonzalez and Ellsbury for Goldschmidt. Again, using the injury to your advantage.
Now, if the owners of those injured guys aren't worried about their injuries, then all of this is moot.
