First Round by Seed
How often each seed advances past the Round of 64, based on all first-round matchups from 2000–2024 (25 tournaments, 1,600 total games).
Key insight: The 12-over-5 upset happens more than 1 in 3 times. The 11, 10, and 9 seeds all win at least 35–40% of the time. True upsets (15 and 16 seeds) are rare but do happen — UMBC made history in 2018 as the first-ever 16 to beat a 1.
Win rate: lower seed vs higher seed (2000–2024)
Detailed breakdown
| Matchup | Higher-seed wins | Lower-seed wins | Upset % | Notable |
|---|
For your picks: 12 seeds are the classic trap — they win about 35% of the time. 11 seeds are nearly 50/50. If you're in vibes mode and two teams feel equally matched, always lean on historical seed data: the 5-seed "safe pick" busts regularly.

Champion pattern: Every champion since 2000 entered ranked in the top 5 of KenPom or an equivalent efficiency metric. Elite defense is the strongest predictor — 22 of 25 champions ranked in the top 15 nationally in defensive efficiency.

The 12-seed mid-major formula: A mid-major 12 seed tends to win when they have (1) an experienced senior-laden roster, (2) elite defensive efficiency, and (3) a slow tempo that disrupts the higher-seed's preferred pace. Think Murray State 2012, Ohio 2012, Oral Roberts 2021.

The 5 things that most predict a tournament run
The Cinderella sweet spot: 11 and 12 seeds from major defensive conferences (Atlantic 10, WCC, MVC, MWC) that play a slow tempo have historically outperformed their seed. In contrast, high-tempo offensive teams seeded 10–14 almost never advance past the first round.
