Dynasty Command
Dynasty Lineup Optimizer
Every league you play in, checked for the same week: which lineups are leaving projected points on the bench, the swap that fixes each one, and any IR or taxi problem that would block a change.
What it checks
Everything the dynasty lineup optimizer looks at.
The optimal lineup for each league's roster slots, against what you have set
Projected points gained by each swap, so the biggest fix is at the top
Projections from StatChasers, Sleeper, ESPN, CBS, FFToday, Fleaflicker or numberFire, or a blend
IR and taxi-squad players who no longer qualify, before the roster locks
One click submits the optimized lineup to a Sleeper league, or to all of them
How it works
Built around your league, not a generic one.
How the optimizer picks a lineup
It fills every starting slot in your league's lineup format with the highest projected players you own, then compares that to what you have set. The difference is the projected points you gain by making the swap. It respects flex and superflex slots, bye weeks and injury designations.
Whose projections
Your choice. The projection source picker offers StatChasers, Sleeper, ESPN, CBS, FFToday, Fleaflicker and numberFire, and you can blend more than one. Every projection-based number in the app follows that setting, so the optimizer, the matchup page and the playoff odds agree.
IR and taxi alerts
Sleeper only lets you keep eligible players on IR and the taxi squad. When a player on IR returns to the active list, or a taxi player no longer qualifies, the roster is invalid and Sleeper will not accept lineup or roster changes until it is fixed. The optimizer finds those rosters across all your leagues and shows the fix.
A real league, this week
Points left on the bench, team by team.
The dynasty lineup optimizer compares each team's lineup as it is set against the best lineup its roster allows under the league's own scoring and slots, and names the one start/sit change worth the most. Below is its output for every team in a real dynasty league.
Questions
Dynasty Lineup Optimizer FAQ
Does the lineup optimizer work for every fantasy league at once?
Yes. It checks every league on your account for the same week and lists the ones with points on the bench first. You can also open one league at a time.
Can the lineup optimizer set my lineups for me?
For Sleeper leagues, once you have verified your Sleeper account, yes: one click submits the optimized lineup to that league, or to all of them. On other platforms it shows the start/sit moves to make and you set them on the platform.
Which projections does the start/sit tool use?
Whichever source you pick, or a blend: StatChasers, Sleeper, ESPN, CBS, FFToday, Fleaflicker or numberFire. The setting applies across the whole app.
Does the lineup optimizer handle superflex and flex slots?
Yes. It fills each slot with the best eligible player for that slot, so a second quarterback lands in the superflex when he projects above the alternatives, and flex slots take whichever position projects highest.
