The NBA is divided into two conferences, East and West, each with three divisions. There are 30 total teams, all of which play in cities in the United States, except for the Toronto Raptors. Although there are divisions within each conference, this does not directly affect whether a team makes the playoffs or not (as in the NFL). The top eight teams (those with the best records) are awarded playoff spots, regardless of where they fall in their division. These teams are then seeded one through eight, again in order of their regular-season record.
Ties in regular-season records are decided by predetermined tiebreakers that have been developed by the NBA, much like the NFL. Although there is a lesser chance of a tie over an 82-game NBA season versus a 16-game NFL season, it does occur. At the end of the 2019 regular season, three sets of teams had identical records. Two of the ties were broken based on head-to-head records during the regular season and the third was based on each team’s record against opponents in their own conference. This is an important aspect as the higher-seeded team will have more home games during each round. All rounds are based on a best-of-seven format. Two games are played in the higher-seeded team’s home venue, then two in the home of the lower-seeded team, before games are alternated until one team has won four games (referred to as a 2-2-1-1-1 format).
