DFEI Defense Ratings (DFEI) represent the per possession scoring advantage a team's defense would be expected to have on a neutral field against an average offense. Unadjusted defensive possession efficiency (DPE) is calculated as a function of defensive game splits. Schedule strength is represented by each team's average per possession defensive opponent adjustment (DOA). Touchdown rate (DTD) is the percentage of opponent offensive drives that result in a touchdown. First Down rate (DFD) is the percentage of opponent offensive drives that result in a touchdown or at least one first down. Available Yards percentage (DAY) is the total yards surrendered by the defense divided by the total yards available to be earned based on starting field position. Explosive Drive rate (DED) is the percentage of opponent offensive drives that average at least ten yards per play. Busted Drive rate (DBD) is the percentage of opponent offensive drives that earn zero or negative yards. Turnover rate (DTO) is the percentage of opponent offensive drives that result in a fumble or interception.

Ratings and supporting data are calculated from the results of non-garbage possessions in FBS vs. FBS games.
