Table of Contents
Analysts are examining various scenarios for the NCAA men’s basketball tournament, ranging from the traditional 64-team format to smaller fields of 48 and 16 teams.
- Projections for the NCAA tournament field are based on data points used by the NCAA Division I basketball committee, including strength of schedule and NET rankings.
- The 2021 tournament will feature at least one fewer automatic qualifier due to the Ivy League’s decision to cancel its season.
- A condensed 48-team bracket would grant byes to the top four seeds in each region.
- A 16-team bracket would select the 16 best available teams, without automatic qualifiers, and limit conference representation.
Projecting the NCAA tournament field is a complex process, mirroring the considerations of the NCAA Division I basketball committee. Analysts, like those focusing on Bracketology, utilize similar data, including strength of schedule, the NET ranking system, and team-sheet data, to forecast which teams will participate in March Madness.

The Standard 64-Team Bracket
Since 1994, the 64-team bracket has been the standard format for the NCAA tournament. However, the 2021 tournament will present some unique circumstances. The most significant change is the decision to host the entire tournament at a single location, eliminating geographical considerations when determining seeding. Furthermore, the number of automatic qualifiers will be reduced to 31 this season, as the Ivy League opted to cancel its 2020-21 basketball season.
A Condensed 48-Team Bracket
In a 48-team projection, the selection process would be streamlined, reducing the number of at-large teams and automatic qualifiers by eight each. However, automatic qualifiers would still receive a revenue unit. The top four seeded teams in each region would receive a first-round bye, leading to four first-round games per region with matchups like 5 versus 12, 6 versus 11, 7 versus 10, and 8 versus 9.
A Smaller 16-Team Bracket
A 16-team projection involves the committee selecting and seeding the 16 highest-ranked teams. Automatic qualifiers would not be included in this scenario, although non-competing conference champions would still receive their designated revenue unit. To ensure national balance, conference participation would be capped at four teams, and no region would feature more than one team from the same conference.
