Source: the NBA’s own Last Two Minute reports. The reports do not say who made each call, so the headline accuracy covers every graded play in this official’s games; the own record and the rank are this official’s part of it. The likely rank range shows how sure the rank is. Officials need a fair amount of graded late-game work before they are ranked. “Vs expected” compares a record with what an average crew would get on the same mix of calls. Whistle tendencies describe how games tend to look with this official working them. They are not a judgment of any single call. Updated each morning; data last built Oct 31, 2026.
