Do all sportsbooks have the same player prop line?

Line shopping usually means the price: -110 here, -105 there. There is a second thing to shop that is easier to miss, because it hides in plain sight: the number itself. Books do not agree on it.

How often the books agree

On our NFL week 3 board, for every player that at least three of eight major US books had posted, we compared the numbers the books hung. The eight are DraftKings, FanDuel, BetMGM, Caesars, Fanatics, BetRivers, theScore Bet and Hard Rock Bet.

On yardage, the books almost never agree. Passing yards had no quarterback on the same number at every book that posted him. Receptions are the exception: there, the books mostly hang the same number.

Count every book on our board, offshore books and bet365’s Ontario prices included, and agreement gets rarer still: the same receiving yards number at every book for 4 of 147 players, and passing yards gaps up to 14 yards.

What a gap looks like

Three players from week 3:

• James Cook, rushing yards: 78.5 at DraftKings, 79.5 at FanDuel, BetMGM, Hard Rock Bet and theScore Bet, 83.5 at BetRivers. A five-yard range for one player’s one stat.
• Amon-Ra St. Brown, receptions: 6.5 at four books, 7.5 at FanDuel and DraftKings. On a receptions line, one catch is the whole bet.
• Travis Kelce, receiving yards: 50.5, 51.5 and 52.5, depending on the book.

When the gap decides the bet

A yard only matters if the result lands on it. So we went back to week 2, which has been played, and checked every NFL prop where the eight books hung different numbers against what the player actually did.

14 of 237. On each of those, the same over won at one book and lost at another. Some of them:

• T.J. Hockenson, 29 receiving yards. Over 28.5 won at BetRivers. At 29.5 (DraftKings, theScore Bet) and 30.5 (FanDuel, BetMGM, Hard Rock Bet), the over lost.
• Cam Ward, 183 passing yards. Over 178.5 won at BetRivers. The other six books had him higher, and the over lost at all of them.
• Christian Watson, 4 receptions. Over 3.5 won at BetRivers and Hard Rock Bet. Over 4.5 lost at BetMGM, DraftKings, FanDuel and theScore Bet.

Receptions stand out. Books rarely disagree on a catch total, but when they did in week 2, the result fell in the gap 7 times in 26. A half-catch line and the next one up are a whole catch apart.

What to do with this

1. Shop the number as well as the price. For an over, the lowest number is the better bet at the same price. For an under, the highest.
2. Weigh the two together. A lower number at a worse price can still be the better bet, and sometimes is not. The Lab shows both side by side so you do not have to do it across four apps.
3. Look hardest at receptions when the books split. It happens less often there, and it mattered more when it did.

How much the price alone is worth is in is line shopping worth it for player props. To see every book’s number for one player at once, open his page in the Lab: James Cook’s rushing yards lists each book on the number it hangs, and the arrows under the chart step between them.

What we counted

Agreement: our board for NFL week 3, 27 and 28 September 2026, as published on Friday 25 September; each book’s own main number for each player, counted where at least three of the eight US books had posted one.

Results: our board for NFL week 2 as published at 12:14 p.m. Eastern on Sunday 20 September 2026, before the afternoon kickoffs, for the 13 games that kicked off that afternoon; each book’s own main number against the player’s final stat line from our game logs. A result “between” the lines is strictly above the lowest number and below the highest. Props we could not match to a stat line were left out.

No sportsbook was contacted. Numbers come from our own board and game logs for NFL weeks 2 and 3, 2026.
