How the fantasy lineup tool works
The fantasy lineup tool reads your lineup from a screenshot, turns sportsbook prop lines into fantasy points under your scoring, and sets the best lineup for the week.

What it reads from a screenshot
Upload a screenshot of your lineup page, plus a second one if the bench does not fit. We read each row: the slot, the player’s name, position and team, the game and kickoff time, your app’s projection, and any injury or bye tag. Roster details shows exactly what we read, so a misread row is easy to spot.
We do not keep the image. The roster and lineup are saved to your account so you can load them again, and you can rename or delete them any time. Each screenshot uses one check. Pricing, changing scoring and loading a saved roster use none.
Where the projections come from
For each player we take the median prop line across the listed sportsbooks for passing, rushing and receiving yards, receptions, passing touchdowns, interceptions and kicking points. A prop line sits where the over and under look about equally likely, so it works as an estimate of the stat. When the price leans to the over, the estimate sits a little above the line. Each stat times its points in your scoring, added up, is the projection.
A stat counts only when at least five sportsbooks post a line for that player, so no single book can set a number. Defenses and players without enough lines, which usually includes kickers, keep your app’s projection, and the tool labels them. A player with yardage lines but no touchdown price is compared on app numbers, so a number without touchdowns never competes with one that has them.
Injury tags come from your screenshot and this week’s official NFL injury report and reserve list, via nflverse (CC BY 4.0). A player listed Out, on injured reserve or on bye counts as 0. If only the report says Out and the books still fully price the player, the lines win, since the report can lag. Questionable and Doubtful players keep their number and get a tag.
How touchdowns are priced
Books post the anytime touchdown market one-sided: a Yes price with no No price beside it. A one-sided price still carries the book’s margin, as the vig guide explains, so it overstates the chance of a score.
We take the median Yes price across books and turn it into a probability, as how to read betting odds shows. Then we scale every player in the game down together until their expected touchdowns add up to the game’s total touchdowns market, which lists both sides and can be fairly priced. When a game has no such market, we take a fixed 8% off, a typical one-sided margin. The five-book floor applies here too.
A 54.4% chance of scoring is about 0.79 expected touchdowns, since some games bring two, and each one earns your league’s touchdown points.
Scoring presets and custom scoring
Choose Half PPR, Full PPR or Standard, or open Customize scoring to match your league. The presets differ only in what a catch is worth: half a point, a full point or nothing. Custom scoring sets every value and adds bonuses, such as 300 passing yards or extra points for tight end catches.
A bonus uses the market’s chance of reaching the mark, so a quarterback with a 40% chance of 300 yards gains 1.2 points from a 3-point bonus. Fumbles and two-point conversions have no market lines and add nothing. Players on app projections keep that number, since your app already uses your league’s scoring.
Locked players and the half-point rule
Once a game kicks off, its players are locked, as they are in your app: a locked player keeps their slot, is never swapped in or out, and no substitution targets that spot.
The tool suggests a swap only when it gains at least half a point. Prices move all week, and a smaller gap can vanish with the next line move. Closer calls among available players are marked too close to switch.
Worked example
- A sample roster priced October 17, 2026, in half PPR: 0.04 points a passing yard, 4 a passing touchdown, −1 an interception, 0.1 a rushing or receiving yard, 0.5 a catch and 6 any other touchdown.
- Matthew Stafford: 281.7 passing yards = 11.27. 2.337 passing touchdowns = 9.35. 0.44 interceptions = −0.44. A 5.6% anytime touchdown chance is about 0.057 expected touchdowns, or 0.34. Total 20.52.
- Derrick Henry: 89.5 rushing yards = 8.95. A 54.4% anytime touchdown chance is about 0.786 expected touchdowns, or 4.72. 1.24 catches = 0.62. 6.5 receiving yards = 0.65. Total 14.94.
- Yahoo projected 21.20 and 15.82. The current lineup was already the best one, so the tool suggested no changes.
Questions
Why does the market number differ from my app?
Your app uses its own model; the market number is what the sportsbook lines add up to. Neither is a promise, and a big gap is a good reason to check the news.
How often do the projections change?
Whenever the lines move, most of all after injury news. Load a saved roster to price it again with the latest lines without using a check.
Is this betting advice?
No. The tool turns public sportsbook prices into fantasy points so you can compare players. Who you start is your decision. 21+ only.
