18 WHAT HAPPENED? GLOSSARY Completion Percentage Above Expectation (+/-) A passer's actual completion percentage compared to their Expected Completion Percentage. Rushing Stats Efficiency (EFF) Rushing efficiency is calculated by taking the total distance a player traveled on rushing plays as a ball carrier according to NGS (measured in yards) per rushing yards gained. The lower the number, the more the rusher can be considered a "North/South" runner. 8+ Defenders in the Box (8+D%) On every play, NGS calculates how many defenders are stacked in the box at snap. Using that logic, DIB% calculates how often a rusher sees eight or more defenders in the box against them. Avg Time Behind Line Of Scrimmage (TLOS) NGS measures the amount of time a ball carrier spends (measured to the tenth of a second) before crossing the Line of Scrimmage. TLOS is the average time behind the LOS on all rushing plays where the player is the rusher. Receiving Stats (WRs and TEs) Average Cushion (CUSH) The distance (in yards) measured between a WR/TE and the defender they're lined up against at the time of snap on all targets. Average Separation (SEP) The distance (in yards) measured between a WR/TE and the nearest defender at the time of catch or incompletion. Average Targeted Air Yards (TAY) The average passing air yards per target for the receiver, by measuring the yards downfield at the time of all passing attempts that the receiver is the target. This stat indicates how far down the field the receiver is being targeted on average. % Share of Team's Air Yards (TAY%) The sum of the receiver's total intended air yards (all attempts) over the sum of his team's total intended air yards. Represented as a percentage, this statistic represents how much of a team's deep yards the player accounts for. Yards After Catch (YAC) The yards gained after a catch by a receiver. Expected Yards After Catch (xYAC) The expected yards after a catch, based on numerous factors using tracking data such as how open the receiver is, how fast they're traveling, how many defenders/blockers are in their space, etc. YAC Above Expectation (+/-) A receiver's YAC compared to their Expected YAC.
