Football Outsiders analyzes the 25 most underrated players of the current decade, going back to 2000. Some of these comments will mention our advanced statistics, including DVOA (Defense-adjusted Value Over Average) -- which takes every play during the season and compares it to the league average based on situation and opponent -- and DYAR (Defense-adjusted Yards Above Replacement) -- which uses a similar method to measure a player's total value compared to a "replacement-level" player.
