The Reliability of the 12-5 Upset
For college basketball fans, the NCAA tournament is synonymous with the thrill of the upset. Among the most anticipated scenarios is the first-round clash between No. 12 and No. 5 seeds, a matchup that has historically favored the underdog more often than casual observers might expect.
Over the last decade, No. 12 seeds have secured victories in 14 of 40 matchups against No. 5 seeds, maintaining a 35% win rate. This aligns closely with the long-term historical performance of 12-seeds since 1985, which stands at 35.6%. In the vast majority of tournaments—34 out of the last 40—at least one No. 12 seed has successfully advanced past the first round, establishing it as one of the most consistent upset trends in sports.
Recent Tournament Trends
While the pattern is reliable, it is not guaranteed. In the last ten years, there have been only two instances—2018 and 2023—where all No. 12 seeds failed to win a game. Conversely, the 2019 tournament showcased the potential of these underdogs, with three different No. 12 teams (Murray State, Oregon, and Liberty) pulling off first-round upsets.
Fan Predictions and Bracket Sentiment
According to data from Yahoo Bracket Mayhem, tournament participants are actively looking for these upsets this year. Among the field of No. 12 seeds, Akron is currently the most popular choice to defeat their opponent, Texas Tech.
Here is how the public is currently backing the No. 12 seeds:
- Akron over Texas Tech: 23.5%
- High Point over Wisconsin: 15.3%
- McNeese over Vanderbilt: 15.0%
- Northern Iowa over St. John’s: 11.4%
As you finalize your own bracket, historical data suggests that backing a No. 12 seed is far from a gamble—it is a statistically sound strategy that has defined March Madness for decades.
