Right now I still see Salty for a SP(Floyd) as happening.
Ells could be traded now if the right deal can be found, but that might take some action to bust up the current Ranger induced log jam FA market before someone is ready to move on a CF. It's also conceivable they hold on to Ellsbury and move him later in the season. Or if the team is doing well and a SP is not needed they could keep him for the whole season and collect a pick after the season. I'm ok with any of these approaches.
Lester
Buchholz
Floyd
Doubront
Lackey/Morales/(FA)
It's not a Washington rotation. But if Doubront continues to progress and everyone else pitches near career averages it's not a bad rotation to start out the season.
Braden, Jurrjens, Hernandez, Liriano, Marcum,and McCarthy are all good one year candidates for depth moves too.
