There are plenty of numbers to crunch before you bet on NBA games. One of the considerations that oftentimes goes overlooked is the officiating. It’s not just players and teams that have statistics—it’s the referees, too.

Here’s how it works: The postseason begins with the top 36 regular-season officials earning spots. They were the highest-rated officials based on performance and NBA rankings. Officials are evaluated after each round of the postseason, with the top ones “advancing.”

The “best” referees are objective, but what we do know is that all officials have trends that bettors can use at their disposal. Those statistics are available to the public, too. We’ll go over that. The first thing to know is that the officiating crew of a particular NBA game is announced the morning of the contest. And while officiating crews are never going to swing a game’s NBA total or points spread—it could be the difference between a few points, and that could be the difference between a win and a loss.

How Referees Impact NBA Point Totals

Let’s take the 2021-22 regular season as an example and look at the difference in officials, how many fouls they call and the points totals of those games. We’ll use 40 games officiated as a minimum threshold, giving us 43 officials to analyze.

The difference in points per game from the highest point total official (227.8) and the lowest point total official (214.8) was 13 points! The number of fouls an official calls is much less of a difference, with just 3.3 fouls the difference between the highest (39.5) and lowest (36.2) number.

NBA Referees: Home vs Away

This isn’t going to surprise anyone, but home teams win in the postseason. But some officials tend to favor the home team more than usual, and the numbers prove it.

We took a look at 2021-22 regular-season numbers and found a big enough discrepancy among refs that it’s something bettors should look at before placing a wager on betting sites.

Among the 40-game threshold officials, the highest win percentage for home teams was .679 and the lowest was .413. That’s a difference of a 56-win team and a 34-win team. That doesn’t necessarily mean grabbing the moneyline of the home or away team based off who’s officiating—and there are three officials to every game—but it’s something to consider.
