PACR stands for Passer Air Conversion Ratio. The formula is
(Passing Yards/Air Yards)
PACR is the most descriptive as well as the most predictive metric we have for quantifying QB passing efficiency. Its partner metric, aPACR, adds in TDs and INTs and is the second most predicitive metric we have for QB efficiency.
What is Exp Comp%?
Expected Completion Percentage is the Comp% we would expect a QB to have based on the depth of each of his throws and the league avergae completion percentage at each. This metric accounts for a QB's distribution of passes, both short and long.
