The NCAA Division I men's basketball tournament brings college teams into a national elimination bracket. Unlike a professional best-of-seven series, a loss ends a team's tournament, which makes each close finish decisive. The early rounds contain overlapping games, while later rounds narrow the audience's attention toward the Final Four and championship game. A bracket is therefore useful navigation: it explains the next opponent and the route still ahead. Keep the edition visible when describing the field. The NCAA's May 2026 announcement says the 2027 men's and women's tournaments expand to seventy-six teams, with opening games before the sixty-four-team bracket. Older sixty-eight-team explainers should not be presented as the current 2027 format.
How the viewing session is organised
Single elimination, opening-round games and a bracket that narrows to the Final Four; edition-specific field sizes matter.
