Our projections. Your build.

Three7 runs on proprietary NFL and MLB projections, with a projected stat line for every player. Then you take control: stack by team and position, set exposure limits, boost the players you like and build lineups the rest of the field won't have.

How our projections work

Built from the stat line up, not the betting line down

Many projections start from Vegas lines and implied team totals, then work backward to fantasy points. Ours aren't built that way: we start by predicting what each player will actually do on the field, then score it.

  1. 1

    Learn from the data

    Machine learning models trained on historical game data, with injuries and who's actually playing factored in.

  2. 2

    Predict the stats

    Passing and rushing yards, receptions, touchdowns: a full stat line for every player.

    7.4 rec · 96 yds · 0.6 TD

  3. 3

    Score it for your site

    Those stats are turned into fantasy points using DraftKings or FanDuel scoring.

    = 19.6 pts

Not Vegas-driven
Betting lines aren't what drive our numbers; the stat models are. When our projections disagree with the market, that's a different angle the rest of the field may not have.
Stats first, points second
Every projection comes with the stat line behind it, so you can see exactly why a player projects where he does, and disagree if you want.
Machine learning, not generative AI
No chatbot writes these numbers. They come from machine learning models trained on real game data and tested against how players actually performed.

Built to differentiate

Our projections are the foundation. Every setting on top of them is yours, so two people using Three7 on the same slate can end up with very different lineups.

Edit any projection
See it differently? Click a projection and type your own number. Captain and MVP rows update with it automatically.
Individual exposures
Set a max exposure for any player right in the projections table, on top of one global cap for the whole build.
Custom stacking
Pick a team and choose how many QBs, RBs, WRs, TEs and a DST to stack from it. Showdown and Tiers stack by team too.
Locks, removes and boosts
Lock in your core, remove players or whole teams, and boost or suppress projections. In Showdown, lock your captain by team, position or player.
Projected stat lines
See the yards, touchdowns and stats behind every projection, not just a point total.
Every DraftKings and FanDuel contest
Classic, Showdown and MVP, Tiers, Total Touchdowns and Total Yards.
Up to 150 lineups per build Premium
Generate a full set of unique lineups in one run, enough for max-entry tournaments, and export them ready to upload.
Settings that save themselves Premium
Your exposures, projection edits, locks, removes and stacks save automatically and are waiting when you come back to the slate.
Bring your own projections Premium
Upload your numbers from a simple template, then blend them with ours at any weight from 0 to 100%. The optimizer builds from the mix.
Saved lineups Premium
Save any build, name it, remove individual lineups and re-export it later, from any device. Encrypted and private to your account.
