2017 NFL season

The 2017 NFL season was the 98th season in the history of the National Football League (NFL) and the 52nd of the Super Bowl era. The season began on September 7, 2017, with the Kansas City Chiefs defeating the defending Super Bowl LI champion New England Patriots in the NFL Kickoff Game. The season concluded with Super Bowl LII, in which the National Football Conference (NFC) champion Philadelphia Eagles defeated the American Football Conference (AFC) champion New England Patriots 41–33 to win their first Super Bowl title, and fourth NFL championship, in franchise history, and making the NFC East the first and currently only division where every team has won a Super Bowl.

For the second time since the league expanded to a 16-game season, a team finished winless in a full season, as Cleveland lost all 16 of their games this season. The last team to do so was the 2008 Detroit Lions.

For the second consecutive year, a team relocated to the Los Angeles metropolitan area, as the former San Diego Chargers announced their intent to do so in January 2017. This was the first time that the Los Angeles metropolitan area had two teams since 1994.

The 2017 NFL League year began on March 9 at 4:00 p.m. ET. On March 7, clubs were allowed to contact and enter into contract negotiations with the agents of players who became unrestricted free agents upon the expiration of their contracts two days later. On March 9, clubs exercised options for 2017 on players who have option clauses in their contracts, submitted qualifying offers to their restricted free agents with expiring contracts and to those who desire to retain a Right of Refusal/Compensation, submitted a Minimum Salary Tender to retain exclusive negotiating rights to their players with expiring 2016 contracts and who have fewer than three accrued seasons of free agent credit, and teams were required to be under the salary cap using the "Top-51" definition (in which the 51 highest paid-players on the team's payroll must have a collected salary cap hit below the actual cap). The 2017 trading period also began the same day.

This season's salary cap increased to $167 million per team, up from $155.27 million in 2016.

A total of 496 players were eligible for some form of free agency at the beginning of the free agency period. Notable players to change teams via free agency included:
