Evolution of Rules Rule changes in the NFL have been made throughout the history of the league to improve the game, make it more exciting and reduce the risk of injury. Safety rules are one of the most important and effective ways in which the NFL and its owners can help protect the health of players. By helping to identify, promote and enforce safe on-field conduct (in concert with off-the-field education and policies), the league seeks to preserve both the health of players and the integrity of the game.
The NFL has established a strong set of rules through the years focused on player safety, designed to promote fair competition while attempting to minimize risk of harm to the player. While many of these rules have focused on reducing contact to the head and neck of players, other changes have protected players from orthopedic and other injuries.
The development of a thoughtful and comprehensive set of appropriately protective rules and policies has always been, and continues to be, an evolving process. The NFL continually evaluates how rules can best be integrated into the game to address safety and health issues.
Each year the NFL Competition Committee conducts a complete review of player injuries and discusses means by which the NFL can reduce them through the implementation of new rules, or by clarifying or strengthening enforcement of existing rules.
Rules the league has established or changed for the protection of players have not only had a positive impact in the NFL, but have subsequently been incorporated at other levels of play, including collegiate, high school and youth programs. Through the NFL's ongoing partnerships and educational initiatives, the awareness of the importance of rules related to on-field conduct and return-to-play, at all levels and ages, is broadened.
