by the way, you may be right about your sense of the JZ talks. He may be a rural kid who is satisfied already with the money he has made and decided to play with house money and see what he could get rather than go the more risk-averse route of taking an offer 4 years ago. We don't know what the terms were of the offer. There did seem like a pretty defined market price of around $30 MM for 5 years right at the time of the first arbitration. If it was offered and turned down, then I agree that he was just going to take it to free agency. If it was not offered, or if the Nats tried to discount it due to the TJ, then I think they fooled themselves. We'll never know.
As for more generally with the Nats, the fact that Harper, Strasburg, Rendon, Espinosa, and others are all Boras clients probably means the Nats have fewer opportunities for deals trading certainty early for free agency years. Ryan Z and Gio went for such deals, Ramos / Storen / Clippard did not, and I'm not sure the latter two should have gotten this type of offer due to the volatility of relievers. It'll be interesting to see what they do with Roark if he has another good year.
