Line shopping — comparing prices across multiple sportsbooks before betting — is the single most impactful habit for improving your sports betting results. And nowhere does shopping matter more than on player props.
Why Props Have More Line Variance
Game line spreads and totals are set by experienced traders who refine numbers across dozens of books quickly. A -3 spread on a popular NFL game will be -3 within 30 minutes at most major sportsbooks because sharp bettors immediately arbitrage the difference.
Player props are different. Books set hundreds of prop lines per slate. They move less aggressively because the volume is lower. Sharp attention is spread across more markets. The result: a player's receiving yards prop might be 64.5 at one book, 67.5 at another, and 62.5 at a third — all at the same time.
Half-Point Differences Add Up
A 2.5-point difference on a prop line seems small. But in a market where the true line should be 65 yards, getting 67.5 on the under vs. 62.5 on the over represents completely different expected values. Over a season, shopping for the best prop line versus taking whatever your primary book offers can add 3-5% to your ROI on props.
Where to Shop Props
Different books specialize in different markets:
- DraftKings and FanDuel typically have the most prop variety and competitive lines on major markets
- BetMGM and Caesars often differ from DraftKings/FanDuel on specific props
- Pinnacle (if accessible) has the lowest vig on props it carries
- Player-specific books sometimes have lines the majors don't
The Optimal Process
- Identify the props you want to bet
- Check 3-4 books for each line
- Bet the best number, regardless of which book has it
- Track which books consistently offer better value on specific prop types
