What's Included?

Unsourced Fantasy Collective provides FanDuel and DraftKings ownership percent projections for each player in every main slate with 6 games or more.

  • UFCollective's algorithm projects the percent of lineups where a player is expected to be rostered. For example, an ownership projection of 23% indicates that UFCollective predicts the player will be on 23% of all lineups.
  • Ownership projections are added a few hours before the lock of the main slate on FanDuel and DraftKings.

Please note that an active RotoWire paid subscription is required to maintain access.

Requires an active RotoWire subscription.
We do not generate projections for Spring Training slates. The values shown are based on each player's average stats from the games they have played so far. Please use discretion when entering lineups based on these values.

    Player Exposure
    Set your minimum and/or maximum desired share of lineups, for each player, when generating multiple lineups at a time.
    This tool can prevent a player from appearing in too many lineups or encourage the optimizer to fit a player into more lineups.
    Individual Players Player Groupings
    Total minimum exposure exceeds 100%. Please consider lowering the minimum exposure for your groups until this message goes away.
    Tips
    • Generate additional lineups if your exposure to a certain group is outside of the min. and max. you entered.
    • Consider increasing the maximum individual exposure, for each player, if group exposure is outside of the min. and max. you entered.

    • Min. %: Force a player to be in x% of lineups.
    • Max. %: Prevent a player from being in more than x% of lineups.

    Examples
    • I want Player #1 to be in at least 10% of lineups.
        Set Player #1's minimum exposure to 10%.
    • I want Player #2 and Player #3 to be in at least 5% of lineups but not more than 15% of lineups.
        Set each player's minimum exposure to 5% and their maximum exposure to 15%.
    • I want to prevent Player #4 from being in more than 25% of lineups.
        Set Player #4's maximum exposure to 25%.

    Notes
    Please note that the optimizer may not mathematically be able to follow your exposure settings if you are generating too few lineups. Simply generate more lineups if you want to get closer to your desired min and max exposure settings.
