Steve Serby at the New York Post has a Q&A with Scott Boras and he asks the agent about his experiences negotiating with George Steinbrenner and Brian Cashman, in addition to many other topics in and around the game. It's an interesting read. Here's what he said on Steinbrenner:

Q: Negotiating with George Steinbrenner?

A: One of the most enjoyable experiences I’ve ever dealt with . . . a true American . . . a great sportsman. Someone who’s very direct, but when information is brought to him, certainly he listened and responded. I really miss working with George, although Hal has demonstrated he has the abilities to carry on the Steinbrenner legacy.

Q: The end of the seemingly endless Bernie Williams negotiations (when Bernie nearly left for the Red Sox)?

A: (George) turned to me and said, “OK partner, we have to make sure this guy does well for the next seven years!”

Q: Your response?

A: “George, we’re gonna look back on this and say Bernie Williams was responsible for at least three World Championships during his career with the Yankees.” He got four. We all felt very good about the outcome of it.
