National Football League playoffs
The season concludes with a twelve-team tournament used to determine the teams to play in the Super Bowl. The tournament brackets are made up of six teams from each of the league's two conferences, the American Football Conference (AFC) and the National Football Conference (NFC), following the end of the 16-game regular season:
The four division champions from each conference (the team in each division with the best regular season won-lost-tied record), which are seeded one through four based on their regular season won-lost-tied record (tie-breaker rules may apply).
Two wild card qualifiers from each conference (those non-division champions with the conference's best record, i.e. the best won-lost-tied percentages, with a series of tie-breaking rules in place in the event that there are teams with the same number of wins and losses[13]), which are seeded five and six.
In each conference, the #3 and #6 seeded teams, and the #4 and #5 seeds, face each other during the first round of the playoffs, dubbed the Wild Card Playoffs (the league in recent years has also used the term Wild Card Weekend). The #1 and #2 seeds from each conference receive a bye in the first round, which entitles these teams to automatically advance to the second round, the Divisional Playoff games, to face the winning teams from the first round. In round two, the #1 seeded team always plays the lowest surviving seed in their conference. And in any given playoff game, whoever has the higher seed gets the home field advantage (i.e. the game is held at the higher seed's home field).
The two surviving teams from the Divisional Playoff games meet in Conference Championship games, with the winners of those contests going on to face one another in the Super Bowl in a game located at a neutral venue that is usually either indoors or in a warm-weather locale. The designated "home team" alternates year to year between the conferences. In odd-numbered Super Bowls, the NFC team is the designated "home team", with the AFC team serving as the home team for even-numbered games.
The NFL is the only one out of the four major professional sports leagues in the United States to use a single-elimination tournament in its playoffs; Major League Baseball, the National Basketball Association and the National Hockey League all use a "best-of" format instead.
