How Regions Affect Tournament Betting
Region assignments are one of the most underappreciated factors in March Madness betting. A team's path to the Final Four is entirely determined by which region they're placed in and the matchups that result.
The Selection Committee aims for balanced regions, but "regions of death" happen frequently — where 3-4 elite teams are concentrated in one bracket. Identifying these imbalances creates betting opportunities, especially for future bets on Final Four teams.
Geographic advantages also play a role. Teams placed in first-round sites near their campus draw stronger crowd support. Our AI factors in venue proximity, conference strength, and historical seed-line upset rates for every matchup in every region.
