The following is CBSSports.com's weekly player rankings, updated as needed on a weekly basis and available each week. The goal of these rankings is to assist you, the Fantasy Football team owner, with setting your lineups.

We invite you to compare these rankings versus our player projections. While you'll surely notice discrepancies between the two, we like to think of our player rankings as a "safer" view of who's worth starting and who's not. Remember, the projections are an estimation based on a three-week average as well as the matchup, while the rankings take into consideration the basic question in Fantasy Football: Who is the better guy to start?

Red and green arrows signify movement during the week. Red boxes indicate an injury, while the yellow, orange and blue boxes indicate that there's news on the corresponding player.
