Uh, where have you been (kidding, joking)?
Remember, they traded for him without asking him if he would from 2nd to OF. Then when he wouldn't move and didn't show up in left they threatened to put him on the unqualified list. It's not that they don't want him. HE DOESN'T WANT THEM - unless they make an offer he can't refuse (which they can't afford to do).
He is so proud to be a second baseman, you think he's going to take a slap in the face from the Nats? Hell will freeze over before he signs with the Nats.
