Establish the role
Current rosters, depth charts, injuries, recent snaps, and sportsbook expectations shape each player's starting role. If someone is missing, team opportunity is redistributed instead of handing every backup an automatic bump.

REVIEW THE PORTFOLIOHOW DFS BUILD WORKS
One process.
Built for each sport.
The workflow stays simple: understand the slate, simulate what can happen, model what the field is likely to do, and choose lineups that make sense together.
ROLE-AWARE · PLAY-BY-PLAYNFL
Follow the role. Then let the game decide.
NFL opportunity is fragile. DFS Build starts with who is expected to play and what their job should be, then lets thousands of possible game scripts change the answer.
DEPTH + INJURIESSNAPS + PROPSGAME SCRIPTOWNERSHIP + FIELD
Simulate the game
Every matchup unfolds drive by drive and play by play. Down and distance, field position, red-zone chances, the clock, and the score all influence where targets, carries, yards, and touchdowns go.
Model the field
Ownership estimates show where the crowd is concentrating. DFS Build creates the opponent lineups you are likely to face, then ranks yours by projected contest finish—not fantasy points alone.
Respect uncertainty
Week 1 gets extra care. Bounded rookie and role priors steady the first projection without pretending uncertainty is gone. As real snaps arrive, what teams are actually doing carries more weight.
HOW FIELD TESTING WORKS
See every lineup as
one entry in a field.
Thousands of game outcomes are only half the problem. DFS Build also models opponent lineups, then ranks each lineup you build against that simulated field.
Simulate the gamesSee a range of outcomes, not one brittle projection.

AN OPTIMIZER SHOULD NOT ERASE YOUR TAKE
Make the machine
obey the thesis.
Your locks, fades, stacks, groups, and exposure limits survive generation. If the rules only support fewer lineups, the rules win.
01 / LEVERAGE
Fade the chalk on purpose.
See ownership, value, and usage together. Lock your conviction, fade the obvious play, and enforce that stance across every lineup.
See the offer02 / PORTFOLIO
Twenty entries are one portfolio.
Control exposure and overlap across the whole portfolio, then compare projected contest finish instead of treating 20 “optimal” lineups as unrelated.
