All advanced statistics are defined in the Football Outsiders glossary with the exception of these defensive stats:
Pct Tm: The percentage of the defense's plays against the run or pass where this player was involved in making the play.
Adj Pct Tm Total: The percentage of the defense's total plays where this player was involved in making the play, adjusted for the number of games he played during the season.
We've created a player page for virtually every player who played at least several games during the DVOA Era (1994-2008), including all offensive players with at least one carry or pass. We also have pages for all 2009 draftees. We currently do not have player pages available for players whose careers ended before 1994 or undrafted 2009 rookies. For older players, we recommend you check out pro-football-reference.com.
All readers can see Advanced Stats for the past three years as well as Game Charting Stats from 2008. Football Outsiders Premium subscribers can see Advanced Stats going back to 1994 (for defense, 1998) and Game Charting Stats going back to the start of the Game Charting Project in 2005.
QB: Quarterbacks are ranked if they have a minimum of 100 pass plays that year (passing) or eight running attempts, not counting kneeldowns (rushing).

At some point in the near future, we'll be standardizing the minimum baseline for defensive backs to be ranked in game charting stats; right now, we're just going by whatever we used in each year's Football Outsiders Almanac or Pro Football Prospectus.
