Drafted good players. Signed them. Added a couple of free agents. Yes, Jayson Werth has helped...and it's only money. They did not have to trade Strassburg / Storen or equivalent for Werth. Extended Ryan Zimmerman.
The owners have money, and they have been smart in spending it.
This is a solid organization: how else could the Nats have survived all the injuries?
Previous baseball owners in Washington did not have the money to compete with the Yankees, with Comiskey and Yawkey and the Hoffbergers. The Lerners do. Clark Griffith, the master trader, did well until baseball went to the "chain store" model, which we now call farm systems. Griffith could only afford a team in Chattanooga. In losing years, he would let the major league roster dwindle -- fail to replace injured players -- as a way to save money.
Consider the difference, and enjoy this team.
