The NCAA Division I men's basketball tournament, known as March Madness, is a single-elimination competition that determines the NCAA college champion. Having been founded in 1939, this yearly event, which includes 68 teams, has become well-known for its unpredictable nature.
The NCAA committee chooses 36 at-large teams, which are announced on Selection Sunday, in addition to the 32 conference winners. Teams compete in seven rounds over a period of three weeks, with seeds ranging from 1 to 16 in four regions.
The Final Four play for the national championship after the First Four, Sweet Sixteen, and Elite Eight rounds of the tournament. The famous "One Shining Moment" montage and net-cutting rituals are held to honor the winning team.

How do the No. 1 seeds perform in March Madness?
Following Kansas's victory as the top seed in the 2022 NCAA tournament, the number one seeds are 147-1 versus the 16th seeds. However, securing the top seed does not guarantee a spot in the NCAA tournament's second weekend. Illinois lost to No. 8 seed Loyola Chicago in the Round of 32 of the 2021 NCAA Tournament, making history as the 20th top seed to lose in the tournament.
The two opening-weekend defeats by top seeds Virginia and Xavier in 2018 served as vivid reminders of the scares that top seeds have had in the past. These losses contrasted sharply with the journeys to the Final Four made by the other two No. 1 seeds that season, Villanova and Kansas.
Consider the 1989 tournament, where two No. 1 seeds, Georgetown and Oklahoma, narrowly avoided elimination from the first round. By a single point apiece, the Hoyas and Sooners upset East Tennessee State and Princeton, respectively. After being in a similar situation the previous year, Michigan State overcame Murray State 75–71 in overtime.
Even though no previous game has ever come down to a single possession, there have been a few notable games in the past where the outcome was determined by only one point. 2012's Syracuse and 2013's Kansas both overcame difficult matches against No. 16 seeds to win by seven points, respectively, over UNC Asheville and Western Kentucky.
Though the first round of a tournament always seems to favor the top seed, anything can happen over the remaining rounds. Even with the overwhelming numbers, only 2008 has seen all four No. 1 seeds appear in the Final Four.
