The Nats wont suck by 2017 but they wont be the juggernaught they are now depending who they lose.
I think they'll sign at least one of Zimmerman/Fister/Stras long-term.
They do have Giolito replacing one of them in the near future.
Fister is the cheapest, Stras has potential elbow problems in the future, and Zimmerman will cost a touch less than what Scherzer got.
Not a fan of Turner replacing Desmond, massive downgrade all-around there. Yunel is a good stop-gap.
