The Overall Performance Index is a data-based model built by Ben Wright. It combines results-based metrics with underlying performance indicators from American Soccer Analysis. Scores are uncapped and grow naturally as the season progresses.
Actual results weighted most heavily. MLS regular season only — no Concacaf, Open Cup, or Leagues Cup.
ASA metric measuring how every on-ball action shifts a team's probability of scoring. Counters luck-based noise in raw results.
Points from the last 5 games divided by 5. A team on a poor run will drop even with a strong earlier record.
Cumulative GF minus GA. A reliable indicator of team quality across the season.
Each week, every team's OPI score is locked and used to measure the quality of opponents faced. Away wins carry more weight than home wins — beating a strong team on the road counts more than beating them at home.
xGF minus xGA via ASA. Shows quality of chances created and conceded — predictive over large samples.
Deviation from 10-year MLS averages (1.75 home, 1.00 away). Rewards teams that outperform location expectations.
The change in a team's OPI score since their last match. A positive delta means the team's overall score improved — a negative delta means it dropped.
A separate indicator showing whether a team's recent form is running above or below their season average. Compares points-per-game over the last 5 matches against their full-season PPG. ↑ hot, ↗ improving, → steady, ↘ cooling, ↓ cold.
Tiers are assigned algorithmically based on each team's OPI score relative to the league mean and standard deviation — they shift week to week as the season evolves.
