The Mavericks posted a 30-11 home record and a 20-21 road record in 2025-26. That 10-game differential is significant. But does crowd noise actually cause it? Let us look at the data.
Home vs. road splits (source: Basketball Reference):
- Home offensive rating: 121.3
- Road offensive rating: 116.8
- Home defensive rating: 111.2
- Road defensive rating: 116.4
The offense is 4.5 points per 100 possessions better at home. The defense is 5.2 points per 100 better at home. Both sides of the ball improve significantly in the AAC.
Free throw disparity:
- Home free throw attempts per game: 24.8
- Road free throw attempts per game: 21.2
- Opponents at AAC free throw attempts: 19.8
- Opponents on the road free throw attempts: 23.1
The Mavs get 3.6 more free throws per game at home and opponents get 3.3 fewer. This is consistent with league-wide home court advantage trends. Source: Basketball Reference.
The crowd factor: Research from the MIT Sloan Sports Analytics Conference (2019) found that NBA home court advantage is primarily driven by three factors:
- Travel fatigue for the visiting team (25%)
- Referee bias influenced by crowd noise (35%)
- Player familiarity with the arena (40% — shooting backdrop, court dimensions, lighting)
The AAC specifically: The AAC's configuration for basketball places fans close to the court with minimal dead space. The lower bowl sections start just 15 feet from the baseline. When the building is engaged (primarily playoff games and marquee matchups), the proximity of the crowd to the court creates genuine pressure on opponents.
The reality check: Home court advantage has been declining across the NBA over the past decade. In 2014, home teams won 57.4% of games. In 2025, that number dropped to 54.8%. Source: Basketball Reference. Better travel, consistent arena conditions, and scouting have reduced the edge.

Player familiarity with the arena at 40% is interesting. The shooting backdrop, the lighting, the depth perception — these are things fans never think about but players absolutely notice.
