The NFL is one of the four major professional sports leagues in North America, and the highest professional level of American football in the world. The NFL's 17-week regular season runs from early September to late December, with each team playing 16 games and having one bye week. Following the conclusion of the regular season, six teams from each conference (four division winners and two wild card teams) title: 2001 Carolina Panthers season text: win: the only other teams in NFL history to win their opener and lose the remainder of their games being the 1936 Philadelphia Eagles and the 1969 Pittsburgh Steelers. The Panthers consequently beat the record for most consecutive losses during a single NFL season shared by the 1976 Buccaneers, the 1980 Saints, the 1981 Colts and the 1990 Patriots.

There are at least five instances in American football in which a team had been shut out throughout an entire season, and four in which a team has shut out all of their opponents in the season (the longest of these being the ten-game perfect season in which the 1933 Providence Huskies did not concede a single point).
