NBA · Ref outlier
100% of high-volume refs trend over the benchmark
Among officials with 50+ games, 53 of 53 finish above the 222.4-point benchmark more often than not.
Why it matters: The over club includes JD Ralls, Evan Scott, Dannica Baroody, Kevin Cutler, Marat Kogut, Biniam Maru, Scott Twardoski, Aaron Smith and 45 more. Target specific refs for overs — league-wide assumptions miss most of the spread.
