Introduced in 2018, the NCAA Net Evaluation Tool (NET) is a ranking system designed to provide a more accurate picture of college basketball team strength and predict their performance going forward. The NET rankings are based on several factors, including wins, losses, strength of schedule, and efficiency, and are used to determine which teams will make the NCAA tournament cut. The NET system does not consider the date of the game, winning percentage, or point margin of victory, but instead focuses on the quality of wins and losses, using a quadrant system to assess the opposing team's strength and location of the game.

What You'll Learn
NCAA Net Evaluation Tool (NET)
The NCAA Net Evaluation Tool (NET) is a ranking system that evaluates college basketball teams' performance and strength. It was introduced in 2018 to replace the RPI system, which had several limitations. The NET rankings are designed to provide a more accurate and sharper picture of a team's strength and worthiness to make the field of 68 in the NCAA tournament.
The NET rankings take into account a variety of factors, including wins, losses, strength of schedule, and efficiency. The Team Value Index (TVI) is a crucial part of the NET rankings, rewarding teams for quality victories, particularly on the road, and considering their net efficiency rating. Unlike the RPI, the NET rankings do not factor in a team's winning percentage or the winning percentages of its opponents. Instead, the NET rankings focus on the quality of wins and losses, utilising a quadrant system to determine the value of each game.
The quadrants, ranging from Quad 1 to Quad 4, are used to assess the quality of a win or loss based on the location of the game and the ranking of the opposing team. Road wins are generally considered more valuable than neutral-site wins, which are, in turn, considered more valuable than home wins. However, the specific ranking of the opponent can modify the value of a victory. For example, defeating a Quad 2 team in January and then witnessing that team advance to Quad 1 by the postseason transforms that initial win into a Quad 1 victory.
While the NET rankings have been praised for providing a more comprehensive evaluation of teams than the RPI, there is criticism regarding the quadrant system's broad categorisation. As of March 15, a road victory at Duke (1) and a road victory at George Mason (73) were considered equal in the quadrant system, which may not accurately reflect the true value of each win. The exact formula or algorithm for calculating NET rankings is not publicly available, but it has become a significant tool for assessing college basketball teams, with daily updates available on the official NCAA website.

Team Value Index (TVI)
The NCAA Evaluation Tool (NET) rankings were introduced in 2018 to replace the RPI system. The NET rankings are designed to provide a more accurate picture of a college basketball team's strength and hence their worthiness to make the field of 68. The NET rankings are a results-driven and predictive metric that takes into account game results, strength of schedule, game location, net offensive and defensive efficiency, and the quality of wins and losses.
The Team Value Index (TVI) is a part of the NET rankings and is solely results-based. It rewards teams for quality victories, particularly away from home, and factors in a net efficiency rating. The TVI only considers games against Division I opponents and is based on results. The algorithm factors in the opponent, location, and winner to produce a TVI score. The exact formula used to calculate the TVI is not publicly available, but it is known that strength of schedule impacts TVI in some way.
The NET rankings are important because they are used by the NCAA Division I men's and women's basketball committees to select, seed, and bracket teams for the championship tournament. The NET rankings are available to track on the official NCAA website and update daily.

Quadrant wins
The NCAA Net Evaluation Tool (NET) is a ranking system that was introduced in 2018 to replace the RPI system. The NET rankings are designed to provide a more accurate picture of a college basketball team's strength and hence their worthiness to make the field. The NET rankings are based on several factors including wins, losses, strength of schedule, and efficiency.
The quadrants in the NET ranking system are used to determine the quality of a win or loss based on the location of the game and the ranking of the opposing team. Quadrant wins are based on the NET ranking of the teams at the time of the game. A team's record against Quad 1 opponents, as well as Quad 2, 3, and 4 opponents, can change throughout the season. For example, a win against a Quad 2 team in January, which becomes a Quad 1 team by the postseason, will be considered a Quad 1 win.
The Team Value Index (TVI) is a crucial part of the NET rankings and is solely results-based. It rewards teams for quality victories, especially on the road, and factors in a net efficiency rating. The NET ranking system does not consider the date of the game, game order, or a team's winning percentage.

Strength of Record (SOR)
The NCAA Net Evaluation Tool (NET) is a ranking system that was introduced in 2018 to replace the RPI system. The NET rankings are designed to provide a sharper, more accurate picture of a college basketball team's strength and worthiness to make the field of 68. The NET rankings are a departure from the RPI rankings, as they take more factors into consideration. Wins, losses, strength of schedule, and efficiency are all factored into the equation.
The NET rankings system does not factor in the date of the game or a team's winning percentage, both raw and adjusted. The point margin of victory by a team is also not factored into the NET rankings. Instead, the NET ranking only factors in the quality of that win or loss. That's where quadrant records, the primary sorting tool for the NET, come into play.

Wins, losses, strength of schedule, and efficiency
The NCAA Net Evaluation Tool (NET) is a ranking system that evaluates college basketball teams based on several factors, including wins, losses, strength of schedule, and efficiency. Introduced in 2018, the NET aims to provide a more accurate assessment of a team's strength and its worthiness to make the NCAA tournament cut.
Wins and losses are a crucial aspect of the NET rankings, but the quality of these wins and losses is more important than the mere quantity. The NET rankings categorize wins and losses into four quadrants, with Quad 1 being the most desirable. The quadrant system considers the game location and the opponent's NET ranking, placing a higher value on road wins and neutral-site wins over home wins. For example, a road victory at a highly-ranked opponent would be considered a Quad 1 win, indicating a high-quality victory.
The strength of schedule is another factor in the NET rankings. It takes into account the opponent strength and the site of each game, assigning a difficulty score. By aggregating these scores across all games, an expected win percentage is calculated, providing a measure of the strength of a team's schedule. This helps evaluate a team's performance in the context of the challenges they have faced.
Efficiency, in the context of NET rankings, refers to a team's offensive and defensive efficiency. The NET rankings consider a team's net efficiency rating, which is calculated by subtracting the number of points allowed on average from the number of points scored on average. A higher net efficiency rating indicates a more efficient team, capable of outscoring their opponents consistently.
While the NET rankings provide a more comprehensive evaluation of college basketball teams, they are not without criticism. Some argue that the quadrant system is too broad, as it does not differentiate between varying levels of difficulty within each quadrant. Additionally, the NET rankings do not consider factors such as game date, winning percentage, or the date of the game, which may impact a team's performance and overall ranking.
