Jamahl Ralls
Own record: −0.4 points vs expected, about average (likely −3.5 to +2.7). That separates Ralls’s part from the partners’, and compares it with what an average official would score on the same mix of calls.

Fouls and free throws with Jamahl Ralls on the crew
Not enough recent games in our data to estimate whistle tendencies for Jamahl Ralls.
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.
