Cinderella Watch

The Cinderella Index identifies underdogs (seeds 9-16) most likely to pull upsets. Each team's predicted tournament wins (from the matchup probability model) are compared against the historical average for their seed. A positive Win Delta means the model expects this team to outperform their seed — they're better than the bracket says. Seed Delta shows the gap between their actual seed and their strength-based predicted seed within the region.

Vulnerable Favorites

The Vulnerability Index identifies favorites (seeds 1-8) most likely to underperform. A negative Win Delta means the model predicts fewer tournament wins than the historical average for that seed — they're overseeded. Seed Delta confirms this: a negative value means the model ranks them lower than their actual seed within the region.
