There isn't a better starting point for unearthing values for FanDuel NFL contests than numberFire's projections tool.
Users can easily view the entire player pool or sort by position to see statistical projections for all players. Additionally, the column for value provides a sortable way to view which players offer the most bang for your buck, showing users the player's points per thousand dollars of salary.
But, of course, factors such as a team's implied total and the game's spread are integral for decision-making. Fortunately, you can peruse the heat map for that information and a wealth of other goodies.
