The NCAA March Madness, often known as March Madness or NCAA March Madness, is a single-elimination competition conducted each spring in the United States to choose the overall winner in Division I men's basketball. It showcases 68 college basketball teams. Harold Olsen, the head coach of Ohio State, came up with the idea for the competition, which was established by the National Association of Basketball Coaches in 1939. It is mostly played in March and has grown to be one of the country's most-watched yearly athletic events.
March Madness Bracket
During the week leading up to the tournament, the Selection Committee—which is made up of conference commissioners and university athletic directors selected by the NCAA—determines the bracket. The Committee frequently creates multiple brackets for various outcomes since the results of many conference tournaments during the same week might affect the bracket.
The committee assigns a genuine seed to each player in the field, ranking them from 1 to 68 to create the bracket. The teams are then divided among the four zones, each receiving a seed between one and sixteen. The "seed line" refers to the same four seeds in each location (i.e., the No. 6 seed line). In the First Four, eight double-up teams battle it out. The seed line for the other two paired teams, the final at-large teams to get bids to the tournament and fight for a seed line in the No. 11 to No. 14 range, fluctuates based on the teams' accurate overall seeding each year. Two of the paired teams play for the No. 16 seeds.
The No. 1 seeds in each area are the top four overall seeds. If all of the No. 1 seeds made it to the Final Four, the regions are matched so that the No. 1 true seed would play No. 4, and the No. 2 true seed would play No. 3. The No. 2 teams are ideally positioned such that the No. 5 true seed and the No. 1 true seed are not grouped together. The committee compares the values throughout the areas and adds up the genuine seed values to guarantee a competitive balance among the top four seeds in each region. Teams will be shifted across areas if sufficient divergence balances the genuine seed distribution.
The top two to four seeds from each conference will be divided among the different regions. If they have played three or more times during the season, twice during the season, or once during the season, teams from the same conference are seeded to prevent a repeat before the regional finals, regional semi-finals, or the second round, respectively. The committee is instructed to avoid rematches from the regular season and the previous year's tournament in the first four. Lastly, the committee will try to prevent a team from being relocated outside their chosen geographic location too frequently, depending on how they placed in the previous two tournaments.
