The DFS Lineup Optimizer and Builder (now one tool) had a major overhaul in September 2018.
The FantasyPros DFS Lineup Optimizer uses the latest daily projections (or weekly, for NFL) to identify which combination of players would produce the greatest production in fantasy points at the lowest cost.
In other words, the Optimizer saves you time by eliminating hours of research each night looking up stats, news, player situations, and trends by using this data to create an optimal lineup.
The projections we use in the Optimizer are constantly being updated; we then use those player projections to create the best possible lineup using the salary available.
Premium users can go beyond the expert consensus lineup by optimizing the lineup in multiple ways. You can filter out or select specific games, use your own projections for players, apply settings for GPP (guaranteed prize pool) games to utilize boom/bust players, view projected percentage rostered, and more.
You can also swap out players, lock in specific players you want to build a lineup around or exclude players and entire teams that you don't think have a favorable matchup.
This lets you tweak the lineup to your heart's content and get an idea of what the projected outcome may look like based on our projections.
The Lineup Optimizer currently supports FanDuel, DraftKings, and Yahoo! contests.
