What are Player Props?

Player proposition bets (props) are wagers on specific statistical achievements by individual players during a game. Instead of betting on game outcomes, you're predicting whether a player will go OVER or UNDER a specified statistical line. Common props include:

  • Points - Will LeBron James score over 25.5 points?
  • Rebounds - Will Nikola Jokic grab over 10.5 rebounds?
  • Assists - Will Chris Paul dish over 8.5 assists?
  • Steals & Blocks - Defensive statistics
  • Three-pointers made - Will Stephen Curry hit over 4.5 threes?
  • Combined stats - Points + Rebounds + Assists (PRA)

The Data Behind the Predictions

GameFocus AI analyzes multiple data sources to generate accurate predictions:

Season Statistics (60% Weight)

We examine a player's entire season performance, calculating averages for points, rebounds, assists, shooting percentages, and more. This provides the foundation - a player's typical performance level.

Recent Form (40% Weight)

Recent games matter more than early season performance. We analyze the last 5-10 games to capture momentum, injury recovery, role changes, and current form.

Matchup Factors

Some teams play faster (more possessions = more opportunities for stats), while others excel defensively against specific positions. We factor in:

  • Pace multiplier - How fast both teams play
  • Defensive ratings - How well the opponent defends each stat category
  • Home/Away advantage - 2% boost for home players

How Our Algorithm Works

Here's a simplified version of our prediction process for a points prop:

Example: Predicting LeBron James Points

  1. 1.Season Average: 25.1 points per game
  2. 2.Last 5 games: 28.4 points per game
  3. 3.Weighted Average: (25.1 × 0.6) + (28.4 × 0.4) = 26.4
  4. 4.Home Advantage: 26.4 × 1.02 = 26.9
  5. 5.Matchup Factor: Opponent allows 5% more points to forwards = 26.9 × 1.05 = 28.2
  6. 6.Final Prediction: 28.2 points

Confidence Scoring

Not all predictions are created equal. Our confidence scores (ranging from 50% to 85%) consider:

Player Consistency

We calculate the coefficient of variation - how much a player's stats fluctuate. Stephen Curry hitting 4+ threes is more predictable than a role player doing the same.

Sample Size

Predictions improve with more games played. Early season predictions carry less confidence than mid-season analysis with 40+ games of data.

Projection vs Line Difference

When our projection significantly differs from the betting line, confidence increases. If we project 28.2 points and the line is 25.5, that's a strong OVER signal.

Understanding Statistical Categories

Basic Counting Stats

  • Points: Total points scored (field goals + free throws)
  • Rebounds: Offensive + defensive rebounds combined
  • Assists: Passes leading directly to teammate scores
  • Steals: Deflections resulting in possession changes
  • Blocks: Shots legally deflected by defense

Shooting Statistics

  • Field Goals Made: Total shots made (2s + 3s)
  • Three-Pointers Made: Shots made from beyond the arc
  • Free Throws Made: Uncontested shots from the line

Combination Props

These combine multiple statistics for higher totals:

  • PRA: Points + Rebounds + Assists
  • PR: Points + Rebounds
  • PA: Points + Assists
  • RA: Rebounds + Assists
