aDOT — Average Depth of Target

AYPRR  — Air Yards Per Route Run

GZ Touches (Green Zone) — Touches occurring inside the opponent’s 10-yard line.

HVT (High-Value Touches) —   Green zone touches plus receptions. Touchdown potential and pass-catching upside are the keys to RB upside in PPR, while rush attempts outside scoring range are far lower in fantasy value.  

LVT (Low-Value Touches) —   Rushing attempts occurring outside of the green zone.  

RACR  (Receiver Air Conversion Ratio) —  Also created by Hermsmeyer, RACR is calculated as total receiving yards divided by total air yards. Similar to yards per reception or yards per target, but per air yard instead.

TPRR  — Targets Per Route Run

TRAP  (Trivial Rush Attempt Percentage) —  For running backs, the percentage of all touches that are not High-Value Touches. A higher TRAP means a high percentage of low-value rush attempts outside scoring range, which is worse for fantasy production.

WOPR  (Weighted Opportunity Rating) —  A metric created by Josh Hermsmeyer which balances team share of targets and team share of air yards. Because a player’s WOPR is a share of his team’s overall opportunity, it’s important to consider team volume as additional context.
