March Madness

The tournament teams include champions from 31 Division I conferences (which receive automatic bids), and 37 teams which are awarded at-large berths. These “at-large” teams are chosen by an NCAA selection committee, as detailed below. The 68 teams are divided into four regions and organized into a single elimination “bracket”, which predetermines, when a team wins a game, which team it will face next. Each team is “seeded”, or ranked, within its region. After an initial four games between eight lower-seeded teams, the tournament takes place over the course of three weekends, at pre-selected neutral sites around the United States. Lower-seeded teams are placed in the bracket against higher seeded teams. Each weekend cuts three-fourths of the teams, from a Round of 64, to a “Sweet Sixteen”, to a “Final Four”; the Final four is usually played on the first weekend in April. These four teams, one from each region, battle it out in one destination for the national championship.
