March Madness is one of the most exciting times for college basketball fans, but the tournament can also be a breeding ground for chaos. Underdog teams stun heavily favored opponents every year, leaving busted brackets in their wake. The term “Cinderella story” conjures an image in your mind’s eye of heart, grit, and sheer determination. However, upsets in the NCAA Tournament are usually driven by cold, complex numbers. Advanced analytics explain why underdogs shock the world and others fall short. If you examine key statistical factors, you can better understand the formula behind March Madness upsets and start to predict which teams might be the ones to cause upsets in this year’s competition.
The Myth of the Cinderella Team
Everyone loves the idea of a scrappy underdog defying the odds and beating seeded teams. Still, most so-called Cinderella teams don’t win simply because of intangible qualities like heart and spirit. Looking closer at past tournament upsets reveals statistical patterns that often indicate whether a lower-seeded team has a legitimate shot at victory. Fans who know where to bet on March Madness usually use the seeding system to give themselves an idea of a team’s strength. However, the seeding system does not always account for stylistic matchups, tempo differences, and other data-driven factors that can swing the game in the underdog’s favor. Historically, teams that pull off big upsets share specific statistical profiles. They excel in three-point shooting, defensive efficiency, and turnover margin. Anyone who examines these metrics can uncover which teams are true Cinderella contenders and who are lucky to be in the tournament.
The Role of Three-Point Shooting
A team’s ability to shoot the three at a high clip is one of the most significant predictors of an NCAA Tournament upset. Three-pointers are becoming increasingly common in the NBA, and that trend filters down to the college level. The math is simple: three points are better than two. The odds of an upset increase significantly if a lower-seeded team can shoot a high percentage from deep while limiting their opponents’ perimeter success. One only needs to look back at UMBC’s historic 16-over-1 upset over Virginia during the 2018 March Madness tournament. UMBC shot an impressive 50% from the three, while Virginia only managed to land 18% of its attempts. The result was a lopsided 74-54 victory for the underdog. Teams that live and die by the three-point shot are risky bets, but when those shots fall, they can neutralize a team with a more talented squad of players, negating the advantages of athleticism and size.
Turnover Margin and Possession Control

Turnover margin is another key factor in tournament upsets. Teams who maximize their possessions by avoiding giveaways and forcing turnovers can shift the game’s balance. A heavily favored team might have more talented players at their disposal, but the door for an upset opens if those star players don’t get enough opportunities to shine. Oral Roberts stunned Ohio State as a No. 15 seed in 2021. A key factor in this upset was that Oral Roberts forced 16 giveaways while committing only six. This gave the underdogs extra possessions, which they converted into crucial points. Teams that excel in ball security and aggressive defense often perform well against higher-seeded opponents because every additional possession increases their chances of winning a game they otherwise might not.
Defensive Efficiency is More Than Just Effort
While defensive intensity is essential, defensive efficiency is arguably more important. Defensive efficiency is measured in points allowed per 100 possessions; it paints a clearer picture of a team’s ability to prevent its opponents from scoring. You tend to find that lower-seeded teams ranking highly in this metric fare well during March Madness because they can disrupt the offensive flow of their more talented opponents. Any team whose defense can suffocate their opponents and hold higher-seeded opponents to below their season scoring averages has an excellent chance of causing an upset.
Pace of Play and Matchup Advantages
Tempo is another overlooked but crucial factor in upsets. Slower-paced teams limit the number of possessions, which reduces the impact of an opponent’s superior talent. Conversely, up-tempo teams can force their opponents out of their comfort zone and gain an edge. Wisconsin often punches above its weight during tournament basketball. They deliberately slow down the game and force more talented opponents into uncomfortable, low-scoring battles where one or two key moments can swing the outcome.
Spotting This Year’s Potential Bracket Busters
How do we use these insights to predict this year’s biggest upsets? The key is to look beyond the traditional seeding and to analyze team metrics. Look for double-digit seeds that rank highly in three-point shooting, turnover margin, or defensive efficiency, and you may uncover a potential Cinderella story. Similarly, find teams infamous for dictating the game’s tempo in a way that could frustrate higher-seeded opponents. Analytics-driven websites identify teams with upset potential each year. For example, in 2023, many pointed to Furman as a team capable of a first-round shock result due to its elite-level offensive efficiency and ability to force turnovers. Sure enough, Furman defeated Virginia, the No. 4 seed.
This year, most basketball fans will struggle to look past the Duke Blue Devils or the Auburn Tigers when picking a team to win the NCAA Tournament. These two college basketball Goliaths have rosters packed with talent destined to play in the NBA one day. However, if teams like the McNeese State Cowboys, the VCU Rams, and the Yale Bulldogs make it to the NCAA Tournament, they could ruffle a few feathers. These underfavored teams are unlikely to go all the way and become college basketball’s champions, but they will enter their first games as underdogs and are capable of causing an upset on the day.
