From the interview (off of mark zuckerman)
Were Nats on your radar before you met with Rizzo and Lerner? "Yeah, absolutely. About the same time I hired Scott [Boras] was about the same time we started talking about the Nationals and possible suitors. Obviously the Phillies had opportunities to sign me long-term, and when that didn't look like that was going to happen, it was about the same time I hired Scott. So right off the bat we were talking about possible suitors for me through free agency, and the Nationals were a team that was at the top of the list because Scott had a relationship with the Lerner family and the organization. He knew how competitive they were and where they were going. He was able to kind of fill me in on what they were all about. They were there from the beginning, I'd say."
