NBAThe National Basketball Association (NBA) is North America's premier professional men's basketball league, composed of thirty teams: twenty-nine in the United States and one in Canada. It is an active member of USA Basketball (USAB), which is recognized by the International Basketball Federation as the National Governing Body (NGB) for basketball in the United States. The NBA is one of the five major North American professional sports leagues, which also include Major League Baseball (MLB), the National Football League (NFL), the National Hockey League (NHL), and Major League Soccer (MLS).
History
1940s and 1950s: The early years
The Basketball Association of America was founded in 1946 by the owners of the major ice hockey arenas in the Northeastern and Midwestern United States. On November 1, 1946, in Toronto, Ontario, Canada, the Toronto Huskies hosted the New York Knickerbockers, which the NBA now regards as the first game played in the league's history.[3] Although there had been earlier attempts at professional basketball leagues, including the American Basketball League and the NBL, the BAA was the first league to attempt to play primarily in large arenas in major cities. During its early years, the quality of play in the BAA was not significantly better than in competing leagues or among leading independent clubs such as the Harlem Globetrotters. For instance, the 1948 ABL finalist Baltimore Bullets moved to the BAA and won that league's 1948 title, and the 1948 NBL champion Minneapolis Lakers won the 1949 BAA title.
On August 3, 1949, the BAA agreed to merge with the NBL, creating the new National Basketball Association. The new league had seventeen franchises located in a mix of large and small cities, as well as large arenas and smaller gymnasiums and armories. In 1950, the NBA consolidated to eleven franchises, a process that continued until 1954, when the league reached its smallest size of eight franchises, all of which are still in the league (the Knicks, Celtics, Warriors, Lakers, Royals/Kings, Pistons, Hawks, and Nationals/76ers).
The process of contraction saw the league's smaller-city franchises move to larger cities. The Hawks shifted from "Tri-Cities" (the area now known as the Quad Cities) to Milwaukee (in 1951) and then to St. Louis (in 1955); the Royals from Rochester to Cincinnati (in 1957); and the Pistons from Fort Wayne to Detroit (in 1957). In 1960, the Lakers relocated to Los Angeles, and the Warriors moved to San Francisco, in 1963. The following year, the Nationals left upstate New York to bring basketball back to Philadelphia, changing their nickname from "Nationals" to "76ers." This means out of the original eight franchises, only the Knicks and Celtics have not relocated at any point.
Although Japanese-American Wataru Misaka technically broke the NBA color barrier in the 1947–48 season when he played for the New York Knicks, 1950 is recognized as the year the NBA integrated. This year witnessed the addition of African American players by several teams, including Chuck Cooper with the Boston Celtics, Nat "Sweetwater" Clifton with the New York Knicks, and Earl Lloyd with the Washington Capitols.
Regular season
Following the summer break, teams hold training camps in October. Training camps allow the coaching staff to evaluate players (especially rookies), scout the team's strengths and weaknesses, prepare the players for the rigorous regular season, and determine the 12-man active roster (and a 3-man inactive list) with which they will begin the regular season. Teams have the ability to assign players with less than two years of experience to the NBA development league. After training camp, a series of preseason exhibition games are held. The NBA regular season begins in the first week of November. During the regular season, each team plays 82 games, 41 each home and away. A team faces opponents in its own division four times a year (16 games), teams from the other two divisions in its conference either three or four times (36 games), and teams in the other conference twice apiece (30 games). This asymmetrical structure means the strength of schedule will vary significantly between teams.
Playoffs
The NBA Playoffs begin in late April, with eight teams in each conference going for the Championship. The three division winners, along with the team with the next best record from the conference are given the top four seeds. The next four teams in terms of record are given the lower four seeds.
Having a higher seed offers several advantages. Since the first seed begins the playoffs playing against the eighth seed, the second seed plays the seventh seed, the third seed plays the sixth seed, and the fourth seed plays the fifth seed, having a higher seed means a team faces a weaker team in the first round. The team in each series with the better record has home court advantage, including the First Round. This means that, for example, if the team who receives the 5 (five) seed has a better record than the team with the 4 (four) seed (by virtue of a divisional championship), the 5 seed would have home court advantage, even though the other team has a higher seed. Therefore, the team with the best regular season record in the league is guaranteed home court advantage in every series it plays. For example, in 2006, the Denver Nuggets won 44 games and captured the Northwest Division and the #3 seed. Their opponent was the #6 seeded Los Angeles Clippers, who won 47 games and finished second in the Pacific Division. Although Denver won its much weaker division, the Clippers had home-court advantage and won the series in five games.
The playoffs follow a tournament format. Each team plays a rival in a best-of-seven series, with the first team to win four games advancing into the next round, while the other team is eliminated from the playoffs. In the next round, the successful team plays against another advancing team of the same conference. All but one team in each conference are eliminated from the playoffs. Since the NBA does not re-seed teams, the playoff bracket in each conference uses a traditional design, with the winner of the series matching the 1st and 8th seeded teams playing the winner of the series matching the 4th and 5th seeded teams, and the winner of the series matching the 2nd and 7th seeded teams playing the winner of the series matching the 3rd and 6th seeded teams. In every round except the NBA Finals, the best of seven series follows a 2-2-1-1-1 home-court pattern, meaning that one team will have home court in games 1, 2, 5, and 7, while the other plays at home in games 3, 4, and 6. For the final round (NBA Finals), the series follows a 2-3-2 pattern, meaning that one team will have home court in games 1, 2, 6, and 7, while the other plays at home in games 3, 4, and 5. The 2-3-2 pattern in the NBA Finals has been in place since 1985.
The final playoff round, a best-of-seven series between the victors of both conferences, is known as the NBA Finals, and is held annually in June. The victor in the NBA Finals wins the Larry O'Brien Championship Trophy. Each player and major contributor -- including coaches and the general manager -- on the winning team receive a championship ring. In addition, the league awards a Bill Russell NBA Finals Most Valuable Player Award to the best performing player of the series.
