NBA Referee Profile
J.D. Ralls
J.D. Ralls has worked 106 NBA games, and the foul data tells you exactly what to expect when he's on the crew. He calls 39.7 personal fouls per game, sitting 2.8% above league average — Ralls reads a tight game and isn't shy about the whistle. That foul volume flows directly into free throw attempts, where he's averaging 46.2 FTA per game, 2.7% above the league norm. If you're handicapping totals, both numbers push toward the over on pace alone. Teams under Ralls get to the line at an elevated clip, which rewards squads that attack the paint and punishes defenses built around deterrence rather than clean stops. Home-court lean is a non-factor here — his home team win rate sits exactly at 50.0%, meaning he's not inflating or deflating home advantage in either direction. Bettors looking to fade home chalk based on referee tendencies won't find an edge with Ralls. Work the foul totals, not the side.
