How it works
How the lineup optimizer works
It solves your league's roster slots against each player's projection in your scoring, respects position eligibility and locks, and compares the result with your current lineup so you see exactly what changed and why.
Fantasy Football Lineup Optimizer FAQ
Does the lineup optimizer work for superflex and 2QB leagues?
Yes. Flex and superflex slots are solved with the same engine, and QB values are weighted for the format.
What is a fantasy football lineup optimizer?
A tool that picks the highest-scoring legal lineup from your roster under your league's slots and scoring. This one does it for every league you play in at once and says what changed and why.
Is there a free fantasy football lineup optimizer?
Yes. Connect a Sleeper, ESPN, Yahoo, Fleaflicker, Fantrax or CBS league and every lineup is optimized at no cost.
Can it set my lineup automatically?
In Sleeper leagues, yes: with a StatChasers account and a verified Sleeper connection the optimized lineup is submitted in one click. Other platforms show the lineup to set by hand.
Does the optimizer handle byes and injured players?
Yes. Players on bye or ruled out are never started, and open IR slots are flagged so an injured starter can be moved to make room.
How is the optimizer different from start/sit?
Start/sit answers one decision between two players; the optimizer solves the whole lineup at once, including flex and superflex slots, across all of your leagues.
