Deciphering NCAA Basketball’s At-Large Bids and Conference Strengths

NCAA basketball fans eagerly anticipate Selection Sunday, the day when the NCAA

Selection Committee announces the teams that will play in the NCAA Tournament. In addition to the 32 automatic bids, the committee grants 36 at-large bids to eligible teams.

These teams must meet specific criteria, including a high win-loss record, efficiency,

RPI, NET rankings, and conference strength. Here, well delve deeper into those topics to explain how the selection process works.

At-Large Bids in NCAA Tournament

The NCAA Tournament, also known as March Madness, is a 68-team tournament that determines the NCAA basketball champion. Of these 68 teams, 32 are automatic bids, given to the conference tournament champions, while 36 are at-large bids.

An automatic bid means that a team has won its conference tournament and secures a spot in the NCAA tournament. So, there are 32 automatic bids.

However, that means that 36 teams must receive at-large bids to fill out the remaining spots.

Types of Bids

At-large bids are given to teams that did not win their conferences tournament but are deemed to have played well enough throughout the regular season to qualify for the NCAA tournament. The committee grants these teams based on various statistics, including their win-loss record, efficiency,

RPI, NET rankings, and conference strength.

Qualification Criteria

Win-loss record

The selection committee closely scrutinizes team records to determine if a team is deserving of an at-large bid. If a team did not win its conference tournament, its win-loss record is a significant consideration in predicting how well it will perform in the NCAA tournament.


The NCAA ranks teams using efficiency data, which combines both offensive and defensive team performance data. The efficiency metric analyzes how effective a team is in scoring, distributing the ball, and preventing its opponents from scoring.

Teams that rank high in efficiency are likely to win games.



RPI or Rating Percentage Index is a statistical method used to rank NCAA basketball teams based on three major factors: a team’s Division I winning percentage, its strength of schedule, and its opponents’ strength of schedule. The committee looks at a teams

RPI ranking to assess their strength of performance relative to the other eligible teams.

Teams with high

RPI rankings usually receive at-large bids.

NET Rankings

In recent years, the NET (NCAA Evaluation Tool) rankings have replaced the rating percentage index as a primary statistic for predicting team performance. The NET system calculates a teams ranking based on their game results and strength of schedule throughout the season.

The NCAA, coaches, and fans claim that the NET rankings provide a more accurate reflection of a teams overall performance.

Conference Strength

Finally, conference strength is a factor considered by the committee in awarding at-large bids. A strong conference means that a team would have had to face high-quality opponents consistently throughout the season, so the committee is likely to consider those teams for at-large bids.

Quantity of At-Large Bids

The NCAA awards a total of 36 at-large bids to teams. The committee typically starts by examining the top eight teams in each conference to determine if any team deserves an at-large bid.

Any remaining spots are then awarded to the remaining teams that meet the NCAA selection criteria.

Selection Process in NCAA Tournament

Selection Sunday is the day when the NCAA

Selection Committee reveals the 68 teams that have qualified for the tournament. For the fans, this is an exciting and nail-biting moment.

The NCAA selection committee is responsible for seeding and selecting the teams for the NCAA basketball tournament.

Selection Committee

The committee comprises ten members who serve for five years. It is a diverse group that includes athletic directors from Division I schools, former head coaches, and the NCAA vice president of basketball.

They meet over several days in a hotel sequestered from the general public. The committee views game footage, discusses performance statistics, and analyzes the rankings to make informed decisions about selection and seeding.

The members are bound by strict confidentiality rules and cannot reveal anything about the deliberations until it is time to announce the final list on Selection Sunday.

Seeding Teams

Once the qualifying teams are decided upon, the committee then has to assign a seeding for each team. The seeding is particularly important as it determines which teams play against each other in the NCAA basketball tournament.

Each team is seeded from 1-16, with the number one seed being the best team in the tournament. The four number one seeds are designated as the top four teams and automatically placed in the four regions.

Eight additional teams are then assigned to each region in order of their seeding. So, the highest-seeded team in each region is placed opposite the lowest-seeded team, with the second-seeded team placed opposite the second-lowest-seeded team, and so on.

Final Thoughts

The process of selecting and seeding teams for the NCAA basketball tournament is a rigorous and detailed process that involves many factors. However, the strict selection criteria, such as win-loss record, efficiency,

RPI, NET rankings, and conference strength, ensure that the best teams get to participate and compete.

It is a thrilling moment when the committee announces the final teams and seeding, and fans eagerly anticipate the exhilaration of March Madness. Conference strength plays a significant role in NCAA basketball, as conferences with stronger teams have a higher chance of receiving at-large bids to the NCAA Tournament.

The Big Six conferencesSEC, ACC, Big 10, Big 12, Pac-12, and Big Eastoften receive priority over smaller conferences, while mid-major conferences such as the American, Mountain West, and West Coast Conferences may get lower seeding in the tournament, despite their strong on-court performances. In this article, well explore how the strength of a conference can impact NCAA tournament bids, and how the committee uses statistics such as

RPI, NET rankings, and conference strength to rank and seed teams.

Priority Given to Big Six Conferences

The Big Six conferences are often prioritized over smaller conferences due to their national appeal, as they often have more supporters and more money invested in their programs. The

Selection Committee tends to give greater consideration to these conferences, resulting in them receiving more at-large bids to the NCAA tournament.

However, this preference for the Big Six conferences is not always fair. In some cases, a smaller conference may have teams that perform just as well as some of the Big Six teams, yet they do not receive the same recognition and opportunities for at-large bids.

Lower Seeding for Smaller Conferences

The committee often gives lower seeding to mid-major conferences such as the American, Mountain West, and West Coast Conference. These conferences consist of schools with smaller athletic budgets, and often struggle to attract top-tier players to compete against larger, more established schools.

Additionally, mid-major teams may have to play a weaker schedule, lowering their rankings compared to teams from the Big Six conferences. This leads to lower seedings, even if they have demonstrated a strong performance throughout the season.

All of this can result in matchups that are less favorable for the smaller conferences. Impact of Statistics on

Conference Strength


Selection Committee uses a range of statistics to determine the strength of conferences as measured against each other.

These include

RPI, NET rankings, and conference strength.

RPI (Rating Percentage Index) calculates a team’s winning percentage, opponents’ winning percentage, and the opponents’ opponents’ winning percentage. This metric is used for selection and seeding, and is a valuable tool when considering a team’s strength of schedule.

NET rankings and conference strength are also used to determine the NCAA tournament seeding. The NET rankings use a combination of offensive and defensive efficiency to rank teams, while conference strength takes into account how different conferences compare to one another based on team performance.

All of these statistics help the

Selection Committee to evaluate the true strength of a team, and how the team’s conference stacks up against others.

Final Thoughts

Conference strength plays a major role in determining NCAA tournament bids. While the Big Six Conferences often receive favorable treatment, mid-major conferences such as the American, Mountain West, and West Coast Conference must often deal with lower seedings and fewer bids.

Ultimately, the selection process is a combination of various factors, including statistics, overall performance, and strength of schedule, that helps determine which teams earn a spot in the tournament. Regardless of the outcome, the NCAA Tournament is an exciting time for college basketball fans as they watch their favorite teams compete for the championship.

In conclusion, conference strength is a crucial factor in determining NCAA tournament bids. The Big Six conferences often receive priority over smaller conferences, leading to mid-major teams getting lower seedings.

By using statistics such as

RPI, NET rankings, and conference strength, the committee evaluates a team’s true strength and how their conference compares to others. As a result, smaller conferences must work harder to overcome the challenges they face in securing at-large bids.

However, regardless of how the teams are selected, the NCAA tournament is always an exciting and thrilling time for college basketball fans. FAQs:
