NBA is the highest-volume prop market — Star and role players get lines nightly for points, rebounds, assists, threes, and combined stats. Here's what actually moves each of them.
Points (typical line: 8.5 – 30.5)
Usage rate. Percentage of team possessions a player finishes with a shot or free throw. High-usage players score more.
Opposing defensive rating vs position. Some teams get scored on by point guards but shut down centers, and vice versa.
Pace. High-pace teams create more possessions per game — more shots for both sides.
Minutes. Blowout risk kills point props. A star who plays 32 minutes in tight games but sits at 26 in blowouts is a different bet.
Rest. Second night of a back-to-back drops production ~5–8% for most players.
Rebounds (typical line: 4.5 – 12.5)
Opponent shooting percentage. Poor-shooting teams create more rebound opportunities.
Pace and rebound rate. More possessions = more missed shots to grab.
Position matchup. Elite rebounders facing an elite rebounder on the other side often get fewer chances.
Minutes stability. Rebound props are extremely sensitive to minutes fluctuation.
Assists (typical line: 3.5 – 11.5)
Teammate shooting. An assist requires a made shot. If a playmaker's teammates are cold-shooting, assists disappear.
Opposing team's foul rate. Fouls disrupt half-court flow and cut into assist volume.
Pace. Same as points — more possessions = more chances.
Style of play. Ball-dominant guards get more assists than off-ball scorers even at the same usage.
Threes made (typical line: 1.5 – 4.5)
Attempt volume. Threes-made props are more about volume than accuracy — a 35% shooter who takes 10 threes usually beats a 45% shooter who takes 4.
Opposing three-point defense. Teams that funnel to the paint concede more open threes.
Recent shooting variance. Threes are the highest-variance prop. Sample size matters more here than for any other stat.
Combined props (PRA, PR, PA)
Points+Rebounds+Assists (PRA) is the most popular combined prop.
Combined props reduce variance because a cold shooting night can still be salvaged by rebounds or assists.
They're often softer at sportsbooks because they're harder to model — sportsbooks assume components are independent when they're not.
