What creates the "one-and-done" scenario is the National Basketball Association (NBA) rule that prohibits a player from graduating from high school and going directly to the NBA. The league's obviously cynical and self-interested rule prohibits a prospect from signing to play before at least one year has elapsed. In contrast, Major League Baseball allows an athlete to be drafted directly out of high school; the National Hockey League organizes competitive leagues that allow high school-age players to move toward their goal of playing professionally. Apart from the world of professional athletics, talented individuals can translate their talent into professional status and income without regard to their age: A supremely talented musician, artist, or actor can gain professional status based solely on his abilities; a basketball player is denied this opportunity until he has completed one year of college. In this commentary, the author asks whether this isn't an obvious violation of the federal prohibition against discrimination on the basis of age. He examines why this rule is allowed and explores the alternatives that do exist.
