Of all the statistics and metrics that Pro Football Focus collects, pass-rush productivity is one of the most important because of the limitations in box score statistics.
Sacks are seen as the end all, be all of pass-rushing, but they are actually an extremely volatile statistic that often owe more to luck and happenstance than a quantifiable, measurable pass-rushing trait.
