This Glossary is intended to put DFS Terms in as simple writing as we deem appropriate. We aim to give beginning DFS players knowledge of how these terms are typically used in the DFS World.
General DFS Terms
Bankroll is the amount of money you’re allocating to your DFS investment. You should never risk more than you’re willing to lose.
Buy In or ‘entry cost’ is the money paid to enter a contest.
Contrarian plays are when you choose a player or lineup that goes against the Chalk. By differing from public opinion you will draft players with lower ownership percentages. The benefit to these plays is that when a low owned player excels it benefits your line up while benefiting a low percentage of the fields’ lineups.
Cash Games typically refer to head to head and double up contest types. Multipliers, boosters, 3 mans, 5 mans, etc are also often included as types of cash games.
Chalk plays are the obvious plays who project to produce great value. The majority of the public will typically recognize this as well, resulting in high ownership of these players.
Defense vs Position or DvP shows how many fantasy point an opposing defense gives up to a players position.
DFS stands for Daily Fantasy Sports.
Double Up‘s are sometimes referred to as ’50/50’s and are a DFS contest type in which nearly half of the field of players doubles their money. The reason less than half the players double there money is due to the entry fee.
Entry Cost is the money paid to enter a contest.
Entry Fee is the portion of a DFS buy in taken out by the DFS site. These fees are how DFS sites make money. Entry Fees are sometimes also referred to as ‘rake’.
Expexted Value (EV) of players in DFS is generally referring to their mean expected performances given a certain set of circumstances.
Expected Value (EV) of an contest entry is generally referring to the expected profit or loss to make on average given a set of circumstances.
Guaranteed Prize Pool Tournaments or GPPs refer to tournament structured contest types in which the prize pool is guaranteed. These contests are guaranteed to run regardless of whether the entry cap is filled. The payout of structure of these contests are top heavy with first place winning the most and each place after first winning less and less.
Head to Heads or Heads Ups are a DFS contest type in which only two players play against each other. The winner wins two times the entry fee they paid minus 2 times the entry fee resulting in almost doubling their entry fee.
Lock is the time when a contest starts and you can no longer edit your lineups.
Must Play is a player who’s value is too good to not play, i.e., the extreme chalk plays.
Overlay is created when there are not enough entrants into a contest to cover the guaranteed prize pool. This excess of prize money means that players with break even expected value (EV) are now profitable players. Profitable players are now even more profitable as there’s essentially free money added to the prize pool.
Projected Value or Points/$ shows a player’s projected score relative to their salary. The formula is (Projected Fantasy Points / Player Salary * 1000). The reason for multiplying by 1000 is just so the number is cleaner, i.e., 2.53 instead of .00253
Team Total is the total for just one of the teams competing in a game. It is (the Total / 2) + or – (the spread/2). See: Total.
Total is the number of points sportsbooks have set for a game. It is sometimes referred to as the “Over/Under” as you can bet that the game will have more or less than the line. High Totals are a good indication of games that will have a lot of fantasy points scored in them.
Vegas Lines refer to the totals, team totals, and the spreads that Vegas or off shore sportsbook use. The best source for spreads is pinnaclesports.com as they tend to have the sharpest lines.
