After the players won the Mackey case in court, the NFLPA and the owners agreed on a new CBA that introduced a new system of refusal and compensation to replace the De Rozelle rule.  The new system still limited the free agency of players.  In the court`s decision, it was stated that compensation for draft choices was to be awarded on the basis of salaries received by outgoing independent agents.  The 1977 agreement significantly improved some medical and retirement benefits for players and achieved a neutral reconciliation of all player/club disputes. In 1982, after the first two games of the season, NFL players went on strike again in an attempt to achieve a guaranteed percentage of the club`s and the league`s revenues.  This strike lasted 57 days, making it the longest work stoppage in NFL history at that time.  The strike ended with an interim agreement on 16 November, which included funds to cover the shortfall in players` wages during the work stoppage.  Negotiators signed a new collective agreement on December 5. The agreement improved player benefits by introducing a new severance pay, increasing the minimum wage for players every year of service and adding new medical rights for players. The agreement also included a revised 1982 season plan, which had a nine-game regular season and a new playoff format that allowed 16 of the league`s 28 teams to qualify for the playoffs.
 In addition, the agreement included the owners` guarantee that players would receive at least $1.6 billion in wages and benefits for the five-year term of the new contract.  After months of negotiations, the longest lockout in league history ended on July 25, 2011 following a preliminary dispute that resulted in the reclassification of some league revenues for cape town. This comparison allowed team owners to prevent a small percentage from being included in future salary caps.  The transaction was conditional on the NFLPA re-forming a syndicate and incorporating the terms of the transaction into a new CBA.   Players reported in July 2011 to training camps and voted in favor of the reunification of the NFLPA as a union. Following the confirmation of the vote on July 31, 2011, the NFLPA began six days of negotiations that resulted in the signing of a new CBA on August 5, 2011.  “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 further progress in player safety and provide our fans with greater and better football,” said NFL Commissioner Roger Goodell.
