Player props are where most +EV opportunities live at US sportsbooks. Here is a practical daily process to find them, and to avoid the many fake edges that props also produce.
Why props produce more edges
Books post thousands of props and cannot keep all of them sharp. Prices move at different speeds after news, and models disagree. The result: more frequent and larger price gaps than on main lines. (Player props guide.)
Step 1: Get a sharp fair line
The best reference is a sharp book or exchange that posts the same prop with both sides. Devig it to get fair over/under probabilities. (How to devig odds.)
When only one sharp source exists, raise your edge threshold. When none exists, consensus across many books (excluding outliers) is a weaker fallback.
Step 2: Handle different lines
Sharp book: Over 6.5 strikeouts at −120. Your book: Over 5.5 at −160. Which is better?
You need the probability of 6+ strikeouts given the fair probability of 7+. A Poisson model with a mean that matches the sharp line's fair probability solves this. (Poisson for props · Poisson calculator.)
Step 3: Compare every book
Compute edge = fair probability × decimal − 1 for each book and each line. Typical prop edges worth betting are 3–8%. (Minimum edge to bet.)
Step 4: Time it around news
- Morning: fresh props, least efficient prices
- Injury reports and lineups: brief windows when books update unevenly
- Close to game time: sharpest prices; edges are smaller but more reliable
Many prop edges last only minutes. Alerts help. (How long edges last.)
Step 5: Filter fake edges
- Big edge + no news check = danger. A role player's points over showing +20% often means the starter is out and the sharp line already moved.
- Different rules: check how each book settles a player who does not play.
- Stale sharp line: if the sharp prop has not updated recently, skip.
- One-sided markets: milestone props ("25+ points") have no opposite side to devig cleanly.
(Stale lines and false edges.)
Step 6: Size and spread
Prop limits are low and variance is high. Use smaller stakes (⅛ to ¼ Kelly) and avoid stacking many props from one player or game, since they are correlated. (Fractional Kelly.)
Step 7: Avoid limits
Prop-only betting at a single book is a fast way to get limited. Spread bets across books, round stakes, and mix in main-line bets. (Avoiding limits.)

Frequently asked questions
Where can I find +EV player props?
By comparing every sportsbook's prop prices against devigged sharp prop lines, either manually or with an +EV screen that covers props.
What is a good edge on a player prop?
Roughly 3–8% from a reliable sharp source. Much larger edges usually indicate news or a stale line.
What time of day are player props softest?
When they are first posted (often the morning or the day before) and right after injury or lineup news.
