A new contract was negotiated in 1970 after the NFLPA merged with the American Football League Players Association.  During negotiations on the new CBA, players went on strike in July 1970.  The new agreement was reached after four days.  The agreement increased the minimum wage for players and changed the league`s medical and retirement programs.  It also provided for an impartial reconciliation of injury complaints, which had been previously decided by the NFL Commissioner.  John Mackey was elected president of the NFLPA during these negotiations and the new agreement was to cover the 1970 to 1973 seasons.  “We are pleased that the players voted in favour of ratifying the proposed new CBA, which will bring significant benefits to all current and retired players, increase employment, ensure continued progress in player safety and provide our fans with greater and better football,” said NFL Commissioner Roger Goodell. “We appreciate the tireless efforts of the executive committee members of the NFLPA Management Board and management, both of whom have spent nearly a year in detailed and good faith negotiations to achieve this comprehensive and transformative agreement. The NFL and its players began negotiating after the players won the Freeman McNeil lawsuit against Plan B. The jury ruled on September 10, 1992, that Plan B was too restrictive under state antitrust law. The team owners then agreed to discuss the free agency for all players.  The NFLPA filed a class action on behalf of Reggie White, claiming that all NFL players should receive criminal damages because of the illegality of Plan B.
The agreement provided for the payment of nearly $200 million in damages and depended on the creation of the NFLPA as a union and the signing of a new CBA that would include the terms of the dispute settlement process.   A seven-year CBA was signed in the spring of 1993, making it the first such agreement since 1987.    The new CBA offered players unlimited free agency after playing four years in the league, subject to an exception for one player franchised per club after the first year of the new CBA. In return, the NFLPA accepted a salary cap based on an agreed percentage of revenue.  The agreement had a direct impact on players` salaries and increased salaries for the 1993 season by 38 per cent.  Based on the progress made since the 2011 agreement and enhanced cooperation between the NFL and the NFL Players Association, a new collective bargaining agreement is in place until the 2030 season.
