Which 1‑seeds are structurally most vulnerable?

• Most vulnerable 1:
Arizona (#2) in the West
• Has to deal with Purdue (#8) and Gonzaga (#11) in-region
• Also faces Arkansas (#16) and Wisconsin (#20) as potential Sweet 16/Elite 8 opponents
• West is the weakest region overall, but Arizona’s path is not soft

Next most vulnerable 1:

Florida (#4) in the South
• Region has Houston (#5), Illinois (#10), Nebraska (#13), Vanderbilt (#17)
• South is loaded with top‑17 teams—Florida’s margin is thin
• Duke (#1) in the East has the hardest region, but also the biggest gap over everyone
• Michigan (#3) in the Midwest has strong opposition, but the region is slightly softer than East/South

2. Where are the most credible non‑1 Final Four paths?

• East:
• UConn (#6)
• Michigan State (#9)
Both are true title‑level teams sitting on 2/3 lines.

• West:
• Purdue (#8)
• Gonzaga (#11)
Either is a completely rational West winner over Arizona.

• South:
• Houston (#5)
• Illinois (#10)
Both are strong enough to win the region without feeling like a “story pick.”

• Midwest:
• Iowa State (#7)
• Virginia (#12)
Both are structurally live to beat Michigan.

2. Where are the most credible non‑1 Final Four paths?
If you want realistic but structurally defensible non‑1s:
• East:
• UConn (#6)
• Michigan State (#9)
Both are true title‑level teams sitting on 2/3 lines.
• West:
• Purdue (#8)
• Gonzaga (#11)
Either is a completely rational West winner over Arizona.
• South:
• Houston (#5)
• Illinois (#10)
Both are strong enough to win the region without feeling like a “story pick.”
• Midwest:
• Iowa State (#7)
• Virginia (#12)
Both are structurally live to beat Michigan.

3. Where does style/volatility create upset pressure?

• Fast‑pace, high‑variance offenses vs slow, efficient favorites
• Heavy 3‑point reliance vs teams that allow a lot of 3s
• Turnover‑prone favorites vs pressure defenses
• Shallow rotations vs physical, foul‑drawing opponents

Those are the spots where a structurally stronger team is fragile, not just “better.”
