Alpha Score Index (ASI) is the world's first football mental performance index. It quantifies what statistics cannot: a footballer's mental readiness to perform. ASI tracks 48 national teams and over 1,100 players heading into the 2026 FIFA World Cup across the United States, Mexico, and Canada. The proprietary scoring system analyses five off-field categories — Harmony, Ecosystem, Stability, Foundation, and Momentum — to produce a 0–100 score for every player. Score bands: Peak (80–100), Stable (60–79), Concern (40–59), Crisis (0–39). Each category is weighted by position archetype: Attackers (Momentum-driven), Creative players (Ecosystem-driven), Defenders (Stability-driven).
