The Nats got Papelbon because they could get him for virtually nothing and restructure his contract to fit in a more team friendly type deal. Rizzo really isn't the type of GM to panic and there is no way you are getting any of the top 5 for Vizcaino. Then you have guys like Difo, Stevenson, Cole that I don't think they would want to part with for a reliever.
I think they go in house with mostly Kelly, but a little bit of Treinen and Perez. I also think they may view Koda Glover (AA-college closer) as the future closer who could be ready this year if really needed. Heck, they would prolly just go cheap and get Clippard back.
