Nats just signed Edwin Jackson to a 1 year deal worth between 8-12 million. The Nats starting rotation now looks like this:
Strasburg
Gio Gonzalez
Jordan Zimmerman
Edwin Jackson
John Lannan/Wang/Ross Detwiler
I suspect Lannan will be traded away now that he's through with his arbitration. I know I'm living in a fantasy world when I say this, but I could see them throwing together a package of Lannan and some of their young talent and making an offer for McCutchen. It would take a lot to pry McCutchen from the Pirates, but the Nats are deep enough now that they could do it.
