The NBA (National Basketball Association) is a renowned basketball league, which consists of 30 teams. These teams are all from different parts of USA, except for one that is from Canada (Toronto Raptors), and they are divided into two conferences: East and West. Each team has a maximum of 15 players signed at a time, thus, making it extremely competitive since only the most elite players in the world participate. Consequently, the level of play is remarkable and the margin of quality between teams is minimal, leading to a very balanced league all around.
The 2019-2020 NBA season will be the 74th of in its history. In the regular season, each team plays a total of 82 games, 41 at their home city and 41 at the opponent’s stadium. Every team plays against the rest of the league at least twice. It begins at the end of October and may last until May. Multiple games occur almost every day, having a sequence of up to 4 games a night. Nevertheless, around the middle of the season (February), the teams take a small pause for the celebration of the All-Star weekend. This weekend rejoices NBA by selecting the best players, rookies, dunkers, three-point shooters to participate in different events. Such as, All-star game, rising stars game, dunk contest and three-point contest.
The NBA post season is called ‘Playoffs’. It begins soon after the regular season ends and last for around 2 months. The league is divided into the eastern conference and western conference, selecting the top 8 teams in each side. The top ranked team, in each conference, plays against the worst ranked team of the same conference (so on and so forth). Thus, it is now an eliminating tournament. All games are best out of seven (first to 4 win) series, consequently the losing team is removed from the Playoffs. After three stages of the playoffs, there are the conference finals. The two winners will compete against each other in the NBA finals. The winner of this tournament becomes the champion of the NBA for that specific year.
The draft occurs once a year during the NBA off-season. It enables NBA teams to select (draft) qualified players to join their team. The draft has two rounds that contain a total of 30 picks (1 per team) each. Thus, each team supposedly acquires two new young players annually. Moreover, team can trade in-between themselves as soon as a player is drafted. Lastly, the best predicted players are chosen higher up in the rank (foreseen best athlete is normally chosen for the first pick). So, in order for the NBA to balance out the league, the worst ranked teams of the season, have higher probabilities of gaining the earlier picks. Then, the NBA establishes the order of teams by random selection.
