This book synthesizes the legal precedents that have shaped the evolution of America's three major sports leagues—Major League Baseball (MLB), the National Football League (NFL), and the National Basketball Association (NBA). It traces the impact of the MLB's antitrust exemption, in juxtaposition to the non-statutory labor exemption of the NFL and NBA. The legal history of each league's constitution and bylaws, collective bargaining agreements and related work stoppages, and uniform player contracts is examined through hypothetical group negotiation and drafting exercises. A discussion of legal challenges demonstrates the unpredictable outcomes created when legal authorities intrude upon the "wonderful world of sports."
