For: One-game playoff A playoff or final in sports is a game or series of games played after the regular season is over with the goal of determining a league champion, or a similar accolade.

Playoffs consist of the teams that won the NL and AL division, plus the two wildcard teams. Playoffs will last up to seven games at the most, and four at the least. The exeption is a one game playoff when the two teams in a division are tied. They'll play and the winner will go to the playoffs.

In the U.S., the vast distances and consequent burdens on cross-country travel have led to regional groupings of teams, usually called divisions. Generally, during the regular season, teams play more games against opponents that are within their own grouping than those outside it. Since every team has not necessarily had a chance to prove itself against every other team, a playoff is necessary every season. Any team that wins its grouping is eligible to participate in the playoffs. As playoffs became more popular, they were expanded to allow teams that finished second or even lower in the grouping to participate. If a team has to be the best of all the lower-ranked teams, these teams are known as wild card teams, such as in the Major League Baseball system.

Playoffs in the National Basketball Association

The present organization known as the National Basketball Association, then called the BAA (Basketball Association of America), had its inaugural season in 1946–1947.

In the current system, eight clubs from each of the league's two conferences qualify for the playoffs, with separate playoff brackets for each conference. In the 2002–03 season, the first-round series were expanded from best-of-5 to best-of-7; all other series have always been best-of-7. In all series, home games alternate between the two teams in a 2-2-1-1-1 format, except for the NBA Finals, in which the format is 2-3-2.

The 2-3-2 finals format was adopted for the 1985 finals, copying the format that was then in effect in the National Hockey League. Prior to 1985, almost all finals were played in the 2-2-1-1-1 format (although the 1971 finals between Milwaukee and Baltimore were on an alternate-home basis, some 1950s finals used the 2-3-2 format, and the 1975 Golden State-Washington and 1978 and 1979 Seattle-Washington finals were on a 1-2-2-1-1 basis). Also, prior to the 1980s, East and West playoffs were on an alternate-home basis except for those series when distance made the 2-2-1-1-1 format more practical.

Teams are seeded according to their regular-season record. The three division champions and best division runner-up receive the top four seeds, with their ranking based on regular-season record. The remaining teams are seeded strictly by regular-season record.

However, the NBA system differs from other sports playoffs in the fact that division champions are not guaranteed home-court advantage at any time in the playoffs, as home-court advantage is decided strictly on regular-season record, without regard to seeding.
