The following player rankings are based on expectations for this week only, not for the entire season, taking into account this week's specific matchups and injuries. The initial rankings are compiled before the release of the NFL's early injury report and are updated Thursday to reflect the status of each player.

We base our rankings on the following scoring system: For skill-position players, one point for every 10 rushing/receiving yards, one point for every 30 passing yards, six points for a TD run or catch, four points for a TD pass, two points for a two-point conversion run or catch, two points for a two-point conversion pass. For kickers, three points for FGs of 18-39 yards, four points for FGs of 40-49 yards, and five points for FGs of 50-plus yards. Defensive rankings are based primarily on points allowed, yardage allowed and sack potential.

Glossary of notations

INJ — player has an injury that may affect productivity or availability.
ILL — player has an illness that may affect productivity or availability.
UP — player was moved up on draft board after original posting.
DOWN — player was moved down on draft board after original posting.
Not listed — player is temporarily sidelined due to injury or suspension but otherwise would be ranked.
