Player transactions refer to the movement of athletes between teams in professional sports. This can include trades, where one team exchanges players with another, or free agency, where players sign contracts with new teams after their previous contracts expire. These transactions are crucial for team strategy and player career development. In addition to trades and free agency, player transactions can also involve drafts, where teams select new talent from college or amateur leagues. The National Football League (NFL), National Basketball Association (NBA), and Major League Baseball (MLB) all have specific rules and timelines governing these transactions to ensure fair competition.
