When it comes to the NCAA Tournament, 15 seeds have delivered some of the most unforgettable upsets in history. Below, we break down how often 15 seeds beat 2 seeds, explore the historical context, and explain how it should shape your bracket strategy.

How Often Does a 15 Seed Beat a 2 Seed?

It has happened 11 times since the field expanded to 64 teams in 1985.

This is dramatically more than the number of times a 16-seed has beaten a 1-seed, but it’s still a very low rate. The 2 seeds have dominated this first-round matchup, with a 149-11 record against 15 seeds, giving them a 93.1% winning percentage.

Some of the most memorable 15-seed upsets include:

  • 2022: Saint Peter’s over Kentucky
  • 2021: Oral Roberts over Ohio State
  • 2016: Middle Tennessee over Michigan State
  • 2013: Florida Gulf Coast over Georgetown
  • 2012: Lehigh over Duke AND Norfolk State over Missouri

What’s the Farthest a 15 Seed Has Gone in the NCAA Tournament?

The farthest a 15 seed has ever advanced in the NCAA Tournament is to the Elite Eight (quarterfinals). This is in stark contrast to 16 seeds, who have never advanced beyond the Round of 32.

Saint Peter’s was the lone 15-seed to make the Elite Eight, which took place in 2022. After upsetting 2-seed Kentucky in the first round, the Peacocks continued their Cinderella run by defeating 7-seed Murray State and 3-seed Purdue before finally falling to 8-seed North Carolina in the Elite Eight.

History of 15 Seeds in the Sweet Sixteen

Other notable 15-seed runs to the Sweet 16 include:

  • Oral Roberts (2021): Advanced to the Sweet 16 before losing to Arkansas
  • Florida Gulf Coast (2013): Reached the Sweet 16 before falling to Florida

This means roughly 2% of all 15 seeds have reached the Sweet 16. What’s particularly interesting is that two of these runs have occurred in the last few years, perhaps indicating that the gap between high and low seeds is narrowing in modern college basketball.

What Does This Mean For Your Bracket?

While historical trends like the 2 vs. 15 matchup data are fascinating, they don’t tell the complete story when optimizing your bracket picks. You need to be careful when applying this information to your bracket strategy.

Our data shows that the general public follows NCAA tournament trends without proper context.

The public often overreacts to recent trends, which creates inefficiencies you can exploit in your bracket pool. While a 15-seed upset happens about once every two years on average, picking the right one is extremely difficult.

More importantly, knowing when to stick with favorites is just as crucial as knowing when to make March Madness upset picks.

The Better (Data-Driven) Approach

The best bracket picks strategy is to find leverage in your bracket based on public biases. At PoolGenius, we show you how to do this by providing comprehensive public pick data and comparing it with the ACTUAL odds a team has to advance.

This helps you identify perfect opportunities to go against the crowd when it makes sense and stand with them when appropriate. Our analysis goes beyond just looking at seed matchups—we examine team strengths, weaknesses, and how each matchup might play out.

Even with 2 vs. 15 matchups, understanding which 2 seeds might be more vulnerable than others requires deeper analysis than just looking at historical percentages. It’s about finding the right balance between playing it safe and taking calculated risks.
