I think they intend to try Christian Garcia as starter, though, they probably won't "count" on that and will sign a FA. Don't see them spending $100 million on Grienke (and I hope they don't) but in the absence of signing EJax, I think they sign an Ejax type pitcher.
Nats will have Strasburg all year, a veteran Gio, a 1 year older and matured, stretched out JZim, a 1 year older and healthier and figured it out, Detwiler - and then a FA/or Ejax redux
Sounds pretty good to me
