Across the history of the major sports leagues in America, labor stoppages have been routinely used to promote competitive balance and long-term labor stability. A byproduct of such lockouts has been salary caps, which attempt to even the playing field when it comes to player contracts and team spending. Keeping Baseball Fair: Salary Cap Advice from the NHL, NBA, and NFL analyzes the processes of lockouts across the NHL, NBA, NFL, and MLB, with a specific focus on how they have shaped salary cap discussions for league regulation. The efforts of this study stem from a love of baseball, a homegrown passion for small-market Cleveland fandom, and a desire to understand the process of salary cap formation. The study examines the successes and failures of the negotiations regarding salary caps for the three other major sports leagues through comparative research displayed on a multimedia website platform, with particular attention to the MLB and its possible future lockout. The research also explores the relationship between the players’ associations of different leagues and the owners and league executives. The project includes an opinionated comparative analysis arguing for the necessity of a salary cap within the MLB, supported by researched evidence from the NHL, NBA, and NFL, and proposed strategies for implementation. This timely research provides insight into the history of labor negotiations, providing an understanding of why the MLB needs a salary cap for an equitable and competitive future.
