The 1971 NFL season was the 52nd regular season of the National Football League. The season ended with Super Bowl VI when the Dallas Cowboys defeated the Miami Dolphins. Before the season, the Boston Patriots changed their name to New England Patriots after they moved to their new home field, Schaefer Stadium in Foxborough, Massachusetts.

Starting in 1970, and until 2002, there were three divisions (Eastern, Central and Western) in each conference. The winners of each division, and a fourth "wild card" team based on the best non-division winner, qualified for the playoffs. The tiebreaker rules were changed to start with head-to-head competition, followed by division records, common opponents records, and conference play. (More tiebreakers were provided in 1971 because, in 1970, reversing just one game's outcome would have led to a coin toss between Dallas and Detroit for the NFC wild-card berth.)

The National Football League has enjoyed success in selling out many of their venues from season ticket sales alone. Out of 32 teams in the league, 24 claim to have waiting lists from under 1,000 people to over 150,000. For some fans, this means a wait not just of years, but decades. This is due mostly to the NFL's short window of play; there are only eight regular-season home games, forcing the most devoted fans into a desperate and sometimes costly search for a limited number of events.

Since 1973, the waiting lists have also had the by-product of preventing any home games of certain teams from being blacked out on local television. Home games must be sold out within 72 hours of kickoff before a telecast is allowed, and the longest waiting lists have ensured every home game of the applicable teams being locally televised. Prior to 1973, home games could not be locally televised even if they were sold out. Four teams have had the benefit of not seeing any blackouts at all since 1972.

Personal Seat Licenses (PSLs) is a license which grants the holder the right to buy season tickets for a particular team. PSLs were first used in the NFL by the expansion Carolina Panthers in 1993 to help finance their new stadium. Since that time, several teams have used the mechanism to finance new stadium projects including the Chicago Bears remodel of Soldier Field and more recently the Dallas Cowboys. The New York Jets and the New York Giants used PSL programs to finance the construction of the New Meadowlands Stadium, now MetLife Stadium.

Howard William Cosell (/koʊˈsɛl/; born Howard William Cohen; March 25, 1918 – April 23, 1995) was an American sports journalist who was widely known for his blustery, cocksure personality. Cosell said of himself, "Arrogant, pompous, obnoxious, vain, cruel, verbose, a showoff. I have been called all of these. Of course, I am." In its obituary for Cosell, The New York Times described Cosell's impact on American sports coverage: "He entered sports broadcasting in the mid-1950s, when the predominant style was unabashed adulation, [and] offered a brassy counterpoint that was first ridiculed, then copied until it became the dominant note of sports broadcasting."

In 1996, Howard Cosell was ranked #47 on TV Guide's 50 Greatest TV Stars of All Time and in 2011 his first full biography, Mark Ribowsky's Howard Cosell: The Man, The Myth, and the Transformation of American Sports, was published.

Cosell was born in Winston-Salem, North Carolina to accountant Isidore Cohen and his wife Nellie Cohen. He was raised in Brooklyn, New York. His parents had wanted him to become a lawyer. He graduated with a bachelor's degree in English from New York University, where he was a member of Pi Lambda Phi. He then earned a degree at New York University School of Law, where he was a member of the law review.
