What does this do? It makes the Nats worse than they could have been, yes, but not all that much worse. Cespedes, unless he's year long a player like he was to end 2015, is not a difference maker by himself. He's a great piece. Revere is an ok one. The Nats should be fine.
Really though it makes the Mets better and probably keeps them ahead of the Nats in terms of favorites for the East. Losing Cespedes would have hurt. Losing Cespedes to the Nats would have put them behind the eight ball. They avoided that scenario. It doesn't mean anything for sure but it's preferable to the alternative that was staring them in the face.
Are the Nats not a desirable location? I think they are fine. Outside of the draw of Madden it's still about money and the Nats are offering fair deals, not great ones. That's smart business but more often than not someone will offer a deal that's great for the player and bad for the team so the Nats lose out. You think they would have learned from Werth and Scherzer, both of who they overpaid, but I guess not.
Still time for stuff to happen.
Quick enough for you?
