Basketball fans and bettors alike are always eager to know the rankings of their favourite teams and players. The NCAA basketball rankings are determined by the Associated Press (AP) and are changed weekly, with polls submitted every Monday. The rankings are based on the votes of 62 sports journalists and broadcasters from across the country, who rank the top 25 teams. Each ranking is given a certain number of points, with 25 points for a first-place vote, 24 for second, and so on. While these rankings have no impact on the tournament, they do spark discussion and give an idea of how the teams are performing. The NET rankings, on the other hand, are the primary tool for evaluating Division I men's basketball teams and are updated daily on the NCAA website.

What You'll Learn
NCAA Evaluation Tool (NET) rankings
The NCAA Evaluation Tool (NET) rankings are an important factor in determining how NCAA Tournament teams are seeded. The rankings are updated daily and are available publicly on NCAA.com and NCAA.org. The NET rankings have been used as the primary tool for evaluating teams since the 2018-19 season, when they replaced the RPI rankings.
The NET rankings are based on a variety of factors, including the Team Value Index (TVI) and adjusted net efficiency ratings. The TVI rewards teams for beating quality opponents, particularly away from home. The adjusted net efficiency rating takes into account the strength of the opponent and the location of the game, with a higher value placed on efficiency against stronger opponents and on the road.
In May 2020, the NCAA announced changes to the NET rankings to increase accuracy and simplify the metric. As a result of these changes, the NET no longer includes winning percentage, adjusted winning percentage, or scoring margin. Instead, the rankings focus on the overall and non-conference strength of a team's schedule, with a difficulty score assigned to each game based on the opponent's strength and the site of the game.
The NET rankings are used by the NCAA Tournament selection committee to evaluate teams and determine their seeding in the tournament. The quality of a team's wins and losses is also taken into account, with higher-ranked wins and lower-ranked losses considered more favourable. This is organized using the quadrant system, which categorizes wins and losses based on game location and the opponent's NET ranking. For example, a win against a highly-ranked team would be considered a Quad 1 win, which is a strong indicator of a team's NCAA Tournament resume.

Associated Press rankings
The Associated Press (AP) rankings are weekly rankings of the top 25 NCAA teams in one of three Division I sports: football, men's basketball, and women's basketball. The rankings are compiled by polling 62 sports journalists and broadcasters from across the nation. Each voter ranks the top 25 teams, and the individual rankings are then combined to produce the national ranking by giving a team 25 points for a first-place vote, 24 for a second-place vote, and so on down to 1 point for a 25th-place vote. The AP releases its rankings every Monday at about 1 PM Eastern Time.
The AP began compiling rankings of the top 20 college men's basketball teams during the 1948–1949 season and has issued this poll continuously since the 1950–1951 season. Beginning with the 1989-1990 season, the poll expanded to 25 teams. The AP also began conducting a preseason poll in 1950. The rankings are based on the opinions of sports journalists and broadcasters and are meant to spark discussion and debate about the best college basketball teams in the country.
The AP rankings are just one of several college basketball ranking systems. Other notable ranking systems include the Coaches Poll, which has been published by various organizations, and the NET or NCAA Evaluation Tool, which replaced the RPI or Ratings Power Index in 2018. The NET rankings are updated daily throughout the college basketball season, while the AP rankings are updated weekly.
The NCAA basketball rankings, including the AP rankings, have no bearing on postseason play. However, the rankings can be used to determine which teams are invited to the NCAA basketball tournament, often known as March Madness. The top 25 teams in the poll are typically invited to the tournament, which features 32 teams in total.

RPI rankings
The NCAA basketball rankings are conducted by the Associated Press (AP) and are updated weekly. AP rankings are determined by surveying 62 sports journalists and broadcasters from across the country. Each voter ranks the top 25 teams, and the rankings are averaged to create the national ranking, with a team receiving 25 points for a first-place vote, 24 points for a second-place vote, and so on. The AP poll releases new college basketball rankings every Monday, typically in the early afternoon (around 1 p.m.) for the East Coast.
While the AP rankings are widely followed, the NCAA previously used the RPI (Rating Percentage Index) rankings in its tournament selection and seeding process. However, starting with the 2018-19 season, the NCAA replaced the RPI with the NET (NCAA Evaluation Tool) Rating. The NET Rating is updated daily on the NCAA website and incorporates the quadrant system, which considers factors such as the location of the game and the opponent's NET ranking.
Despite the NCAA's shift to the NET Rating, the RPI rankings still hold some relevance. The NCAA reportedly uses a Strength of Schedule ranking derived from the RPI during the team selection process. Additionally, comparing the RPI and NET rankings can provide valuable insights and context for evaluating teams.
It is worth noting that the NCAA rankings, whether based on RPI or NET, do not directly impact the postseason tournament selections. The college basketball poll has little influence on the postseason, as 68 teams are included in the Division I postseason tournament, with seeding determined by seasonal on-court results. Nonetheless, the rankings spark discussions and provide a snapshot of how the teams are performing.

Quadrant system
NCAA basketball rankings are typically updated on a weekly basis, with polls submitted every Monday. The rankings are conducted by the Associated Press (AP), with 62 sports journalists and broadcasters from across the country participating in a survey to determine the top 25 teams. Each voter ranks their top 25, and the rankings are averaged to create the national ranking, with a team receiving 25 points for a first-place vote, 24 points for second, and so on.
Now, let's delve into the Quadrant System, which is an integral part of these basketball rankings.
The Quadrant System:
The Quadrant System is a crucial method for evaluating and ranking college basketball teams. It is a four-section model that takes into account various factors, including the location of the game and the rankings of the opposing teams. This system is used in conjunction with the NCAA Evaluation Tool (NET) rankings, which replaced the Ratings Percentage Index (RPI) as the primary tool for assessing teams before the 2018-19 season.
The Quadrant System helps to contextualize a team's performance and provides a more nuanced understanding of their strengths and weaknesses. It considers factors such as home, away, or neutral game locations and the rankings of opponents, with the top two quadrants being the most significant.
Quadrant 1 wins are highly valued and refer to home games against teams ranked 1-30, neutral games against teams ranked 1-50, and away games against top-ranked opponents. These wins can significantly impact a team's tournament selection chances.
Additionally, the NET rankings also consider other metrics such as the ESPN Strength of Record and BPI rankings, the KPI, KenPom, and Sagarin rankings. These metrics provide a comprehensive view of a team's performance, considering factors like scoring margin, net offensive and defensive efficiency, and strength of schedule.
In summary, the Quadrant System, in conjunction with the NET rankings, offers a sophisticated tool for evaluating college basketball teams. It provides context to a team's performance, rewards them for beating strong opponents, and helps determine their tournament seeding and selection.

Team Value Index (TVI)
NCAA basketball rankings are typically updated on a weekly basis, with polls submitted every Monday. The rankings are determined by the Associated Press (AP), who survey 62 sports journalists and broadcasters from across the country. Each voter ranks their top 25 teams, with points allocated for placement (25 points for first place, 24 for second, and so on).
Now, let's delve into the Team Value Index (TVI) component of the NCAA Evaluation Tool (NET) rankings. The TVI is a results-oriented element of the NET rankings, designed to reward teams for defeating strong opponents, particularly in away games. It is one of the two main components of the NET, the other being adjusted net efficiency. The NCAA has not publicly disclosed the exact formula for calculating NET rankings, and the proprietary algorithm is closely guarded.
The TVI specifically considers games against Division I opponents and is based solely on results. The algorithm takes into account the opponent, location, and outcome of the game to generate a TVI score. While the exact calculation method remains a secret, we know that the strength of the schedule plays a role in the TVI. The NCAA implemented the NET rankings for the 2018-19 season, replacing the Ratings Percentage Index (RPI) system.
The NET rankings are not solely based on winning percentage but consider various factors, including game results, strength of schedule, game location, net offensive and defensive efficiency, and the quality of wins and losses. The NET system also utilises a quadrant system, categorising teams from Quadrant 1 (the best) to Quadrant 4 (the worst) based on their performance and strength of wins and losses.
