What player props are, and how they work

A player prop is a bet on one player's numbers in one game: points, rebounds, assists, threes, or a mix of them like points + rebounds + assists. You don't care who wins. You care whether Jalen Brunson scores more or fewer than the number the bookmaker set.

The line

The bookmaker sets a line, say 24.5 points, and you pick a side:

• Over: he scores 25 or more.
• Under: he scores 24 or fewer.

Lines end in .5 so there is no tie. When a line is a whole number (24) and he scores exactly 24, the bet is a push and your stake comes back.

How the line is set

The line is the bookmaker's best guess at the middle: the number where half the money goes each way. It starts from the player's averages, then moves with everything the market learns during the day:

• his recent form and his minutes
• the opponent: pace, defense, how they guard his position
• injuries on both teams (a missing teammate means more shots for someone)
• where the money goes: lines move when bettors pile onto one side

That last point matters. A line is not a prediction of what will happen. It is a price that balances the bets.

What decides a prop

Almost every prop comes down to two things: minutes and role. A player can't score without playing. Before you look at anything else, ask:

1. How many minutes is he likely to play tonight? Is there a blowout risk, a back-to-back, a minutes limit?
2. What is his role? Is a teammate out, so he gets more shots or more time with the ball?

Then come the matchup, the pace of the game and his recent form.

Points, rebounds, assists, and the rest

• Points have the most information behind them and the most efficient lines.
• Rebounds and assists swing more from night to night, so the lines are a little looser, and the matchup matters more.
• Threes are lumpy: a shooter can go 1 for 9 on good looks. Look at attempts, not just makes.
• Combos (points + rebounds + assists) smooth out the swings, because a bad night in one stat is often made up in another.

Where to start

Pick one player you know well. Look at his last ten games against tonight's line, his minutes, and the opponent. That is the whole job, done carefully.
