Marvin Miller was the first executive director of the Major League Baseball Players Association. The story of his experiences in baseball is a compelling one. No one else can take fans into the conference room where headline-making deals of the past quarter century were hammered out. Many can cite the career statistics of such stars as Willie Mays, Tom Seaver and Reggie Jackson; no one but Miller can reveal how these players and other greats behave in their business suits, when facing their toughest opponents: the owners, general managers and commissioners who kept the wealth of major league baseball out of the player's pockets for a century.
