Pro Football Focus’ in-depth charting and advanced stats look beyond the box score to identify key metrics otherwise overlooked across all positions in the NFL. This “Signature Stat Spotlight” series will walk readers through the varying advanced stats and metrics we track for every player at every position in every game.


PFF’s quarterback charting continues to grow, as well. Our analysts have now started to chart quarterback decision (i.e., first read, checkdown), targeted route, incompletion type (i.e., dropped pass, pass breakup) and much more as we continue to develop our skills, add to our staff and learn more about the stable, valuable elements of quarterback play.  Read more…

Running Back:

In addition to grading all of the NFL’s running backs via our advanced grading process, PFF tracks forced missed tackles, yards after contact, elusive rating and breakaway percentage in Premium Stats 2.0, our advanced statistics database made available to all of our ELITE subscribers.  Read more…

Wide Receiver:

In addition to yards per route run, PFF tracks passer rating when targeted, drop rate, deep receiving statistics and slot production in Premium Stats 2.0. Outside of ELITE, PFF also charts contested targets, receptions, etc. and forced missed tackles and yards after contact on receptions. Read more…

Offensive Line:

Hurries, hits and sacks allowed all come into play for offensive linemen, as does PFF’s pass-blocking efficiency metrics, which measures pressures allowed on a per-snap basis with weighting toward sacks allowed. The formula:  1 – (Sacks + Hits) / (2) + (Hurries) / (2) / (Total Pass-Block Snaps) * 100. All of which can be found in Premium Stats 2.0, which is made available to our ELITE subscribers. Read more…

Defensive Line:

Pivoting from offensive linemen to defensive linemen, I’ll discuss hurries, quarterback hits, sacks, defensive stops, batted passes, missed tackles, and all of the advanced stats pulled from the charted stats above. Charting pressures (i.e., hurries, hits, sacks) allows us to calculate pressure percentage (total pressures/pass-rush snaps) and PFF’s pass-rush productivity (PRP) metric. The formula for PRP: ((Sacks + Hits) / 2) + (Hurries) / 2)) / (Pass-Rush Snaps). Read more…


Moving on to linebackers in our Signature Stat Spotlight series, we’ll discuss tackling efficiency (attempted tackles per miss), run-stop percentage, passer rating allowed, yards after the catch per reception allowed, pass-rush productivity among other advanced stats tied to linebackers in PFF’s Premium Stats 2.0. Read more…


Safeties need to be versatile in today’s NFL. The best at the position can thrive from any pre-snap alignment, play the run and make plays both in coverage and rushing the passer. As such, all of PFF’s advanced stats and pre-snap charting tied to defensive players apply to today’s safeties. Read more…


Charting targets, receptions allowed, yards allowed, touchdowns allowed and forced incompletions serves as the core of what we use in our advanced stat formulas for cornerbacks. With the aforementioned information, we can pull yards allowed per coverage snap, targets per coverage snap and receptions allowed per coverage snap. We calculate passer rating allowed, yards after the catch allowed and catch percentage allowed (receptions allowed/targets), as well. Read more…
