Each label is the year the season ended. Bars start at 80%.
03 · Where the misses are
Miss rate by call type
Share of graded plays the NBA’s report marked as errors, for call types with 50 or more graded plays, next to the league rate for the same type. The five highest are shown.

| Foul: Loose Ball | 58 | 8.6% | 7.8% |
| Foul: Offensive | 74 | 6.8% ↑ | 4.6% |
| Foul: Shooting | 171 | 6.4% | 6.0% |
| Foul: Personal | 135 | 3.7% | 4.2% |

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.
