Which Mid-Seeds Go Deep?
The Sleepers With Sweet 16 Written All Over Them
Mid-seeds (4+) peaking in their last 10 games with a top-half schedule strength reach the Sweet 16 at a 62% rate — 4.4× the base rate for their seed range. 23% make the Elite 8. This signal surfaced UConn's 2023 title run, Alabama's 2024 Final Four, and Auburn's 2019 Final Four.

The Seed-Line Playbook
16 Games. ~7 Upsets Per Year. Here's How to Pick Them.
Since 2008, seeds 5-12 through 8-9 produced an average of 7 upsets per tournament — nearly half flip. But they’re not random. Each seed line showed different historical patterns: coaching experience (5v12), defense and coaching (6v11), team quality (7v10), or no reliable signal at all (8v9). Understanding these tendencies can help you pick more of them right.
272 games · 17 tournaments · 2008–20251.8× more likely than averageA-
In 5v12 games, coaching experience was the strongest historical signal — it mattered more than Power Rating in our sample.
41%
upset rate
28/68 games
Consider 1–2 upset picks— 1.5 per year — this seed line often produces at least one upset
Rule of Thumb
If the 5-seed coach is lightly tested and the game looks close by the numbers, upset risk rises. Historically, first-time coaches won only 25% of the time. Veterans (8+ appearances) won 62%.
The Evidence
5-seed coaching wins gap (+5.2) was the strongest historical upset signal across all seed lines we studied
5-seeds shooting below 50% EFG% lost 60% of the time (vs 41% base rate) — the 5-seed’s shooting efficiency is a useful secondary check
12-seeds with experienced coaches (3+ appearances) won 45% vs 33% for first-timers — the underdog’s coach matters too
What Doesn't Matter
Power Rating (PR) gap between survivors and victims was only 0.7 — too close to separate. The gap helps gauge competitiveness, not who wins
Schedule strength (SOS) was identical at 0.7 for both groups — no edge here
Based on historical tendencies, not predictive certainties. Power Rating (PR) measures team quality from adjusted efficiency.

Top Seed Report Card
This Is One of the Strongest 1–4 Seed Fields Since 2008
Alabama (#4, AdjDE 102.8) and Arkansas (#4, AdjDE 101.7) are the only weak spots in an otherwise rock-solid field. Top seeds with defense worse than 100 have won just 67% of first-round games since 2008. Every other 1–4 seed cleared a Power Rating of 92 — only the 2nd time that’s happened.
272 seeds 1–4 · 2008–20251.3× more likely than averageA
Defense↑ Better DefensePoints allowed per 100 possessions
Showing seeds 1–4, 16 teams
Power Rating→ StrongerOverall team quality (0-100)
All 16 seeds 1–4 are shown. Only Alabama and Arkansas sit below the defense danger line (AdjDE > 100) — the rest of this field is historically strong.
Reading the chart: Lower AdjDE = better defense. This metric estimates points allowed per 100 possessions, adjusted for opponent strength. A team at 95 allows roughly 5 fewer points per game than a team at 100.
This is the 2nd consecutive year every 1–4 seed cleared a Power Rating of 92 — it never happened before 2025. The NIL era may be concentrating elite talent at the top, making the favorites harder to upset but also raising the defensive floor. Before NIL, the average top-seed defense was 91.7; since 2022, it's 93.8.
The Two to Watch
Why the Defense Line Matters
These top seeds crossed the defense danger line and paid for it with first-round exits. This year's field is strong enough that only two 4-seeds are near it.

Cinderella Runs
These Double-Digit Seeds Could Go Deep
Unlucky teams (luck < 0) with Offense > 112 reached the Sweet 16 at a 17% rate as double-digit seeds.
Negative luck means a team won fewer games than their stats predicted — they're better than their record and seeding suggest.

47 power-conf teams · 2008–20251.4× more likely than averageB+
Only 2 of 68 1-seeds have lost in the first round since 2008. Both had warning signs:
Virginia 2018
Power 97.0 · Defense 85.1 · Tempo: slowest in field
Lost to UMBC — first 16-over-1 ever
Purdue 2023
Power 93.9 · Defense 94.3 · Weak D for a 1-seed
Lost to FDU — weakest D among 1-seeds that year
Both upsets had a profile: Virginia's slow tempo made digging out of a double-digit deficit extremely difficult, while Purdue had the weakest defense among that year's 1-seeds. The 2026 class looks clean — no pace outliers, and even the weakest defender (adjDE 92.3) sits below Purdue's 94.3 danger zone. The ranking below shows relative vulnerability among this year's 1-seeds, not actual upset risk.
