Team grades

Descriptive team-performance grades, not win probabilities. Each measure is normalized against the complete 30-team sample with a normal-CDF z-score (equal values score 50). Offense and defense adjust for opponents’ season efficiency; recent form uses the last ten opponent-adjusted margins. Rebounding uses team share versus opponents’ average rebounds, turnovers per 100 estimated possessions, shooting uses effective field-goal percentage, and consistency uses margin variability. Possessions: FGA − OREB + TOV + 0.44 × FTA. No sportsbook inputs.

Weights: offense 20% · defense 20% · net 20% · schedule 5% · recent 10% · rebounding 8% · turnovers 7% · shooting 5% · consistency 5%. Boundaries: A+ ≥90, A ≥80, B ≥70, C ≥60, D ≥50, F <50. These transparent initial weights are not claimed optimized or predictive. No current grade is generated without complete evidence; snapshots record actual capture time, never fabricated historical dates.
