5. What will happen to John Lannan?
The Nationals are open to trading Lannan, but they insist they'll deal him only at their price. With Zimmermann, Wang and Strasburg all recently recovered from surgery, the Nationals know they need insurance. If they can't find a desirable return for Lannan, they could stash him at Class AAA Syracuse to start the season because of his remaining minor league option, which would be surprising given his solid performance and his $5 million salary. For now, he'll compete for a spot and give the Nationals luxury. If they suffer an injury in their rotation, they'll have a more-than-capable replacement. And if (or, more likely, when) another team loses a starter to injury, the Nationals can use their surplus to pry a valuable player in a trade.
