The chart below represents pass rush efficiency for each of the defensive tackles. The metric PRR, pass rush rate, measures how often the pass rusher affected the QB in the form of a pressure, sack, or knockdown. PRR+ includes pass deflections at the line of scrimmage. The number represents on a per snap basis, how often they get to the QB – ie, if PRR is 10 it means they affect the QB once every 10 snaps. Thus a lower number is better.
