Ownership and Leverage in DFS Tournaments

Ownership is the percentage of lineups in a contest that include a given player. Before lock you can only estimate it, using tools that project ownership from salary, matchup, news and popularity. After the contest, the actual ownership is shown in the contest results.

In cash games, ownership barely matters. In large tournaments, it is one of the most important numbers on the slate.

Why ownership matters in tournaments

To finish at the very top of a large tournament, your lineup has to outscore nearly everyone else. If a player is in 40 percent of lineups and has a great game, he lifts 40 percent of the field along with you. You gain little ground on the field by rostering him. If you roster a player who is in 3 percent of lineups and he has a great game, you jump ahead of almost everyone.

That is the core idea behind leverage: a player's value in a tournament depends both on how likely he is to have a great game and on how many of your opponents have him if he does.

Leverage is not contrarianism

The common mistake is to treat low ownership as a goal in itself. A player who is lightly owned because he is in a bad spot is not leverage. He is just a bad play. Leverage comes from players whose chance of a big game is higher than their ownership suggests.

A useful way to frame it: compare how often you think a player finishes as one of the best plays on the slate with how often the field is rostering him. If you think a receiver has a 10 percent chance of being the top scorer at his position and he is projected at 4 percent ownership, he is underowned relative to that outcome. If the most popular running back on the slate is projected at 45 percent ownership but you think his chance of a slate-winning game is closer to 25 percent, the field may be overweighting him.

Popular players still belong in good lineups

Popular players are popular for a reason: they are usually in good spots at fair prices. Fading every highly owned player means giving up a lot of expected points. A more balanced approach is to roster some popular players, then create separation in other places: an unpopular stack, a less obvious bring-back, or a different way to spend your salary.

Total lineup ownership, the sum of every player's ownership in the lineup, is a simple way to check how unique a lineup is. Very high totals mean you are close to the field. Very low totals often mean you've given up too many projected points to be different.

Where differentiation comes from

• Stacking a game the field is overlooking.
• Pairing a popular quarterback with a less popular pass catcher.
• Using an uncommon salary structure, for example spending up at tight end or defense when most lineups spend up at running back.
• Leaving some salary unused when it lets you build a lineup the field won't.
• Taking the opposite side of a popular game script, like a team that is expected to run the ball but may need to throw.

Ownership projections are estimates

Projected ownership can move a lot in the final hours before lock, especially after injury news. Treat projections as a guide rather than a fact, and expect the biggest errors around late news and cheap replacement players who suddenly have a clear role.

Finally, contest size matters. In a small single-entry contest, standing apart from the field matters less, because you need to beat fewer people. In a contest with tens of thousands of entries, ownership becomes far more important.
