• Adjusted Protection Charge takes into consideration profitable protection charge for a participant or protection and expands it to account for earlier than PFF graded each protection participant on a play.
• By this metric, the New England Patriots have fielded essentially the most profitable secondary over the previous 5 seasons.
• Among the many high cornerbacks in Adjusted Protection Charge since 2006 are Darrelle Revis, Richard Sherman and Marshon Lattimore.
Among the many high safeties in Adjusted Protection Charge since 2006 are Jevon Holland, Anthony Harris and Trevon Moehrig.
PFF’s protection grades date again to 2006, however since 2019, protection grades are awarded to each defender in protection on each play as a substitute of solely these focused or concerned in a play. Utilizing this new knowledge, we’re capable of calculate every participant’s profitable protection charge — the proportion of the time a protection defender earns a grade of “zero” or larger on a play.
I beforehand created a metric that used participant mix knowledge to foretell eventual NFL protection charge. Since we solely have this whole knowledge from the 2019, 2020 and 2021 NFL seasons, this solely included gamers who have been drafted since 2019. Nonetheless, what if we expanded this to incorporate all gamers since 2006? Utilizing a newly created adjusted protection charge, we are able to see which gamers and groups carried out the most effective in protection, mixed with different stats reminiscent of move breakup charge and common anticipated factors added (EPA) allowed.
A defender’s uncooked protection charge is the proportion of time they earned a “zero” protection grade or higher on relevant performs (the place the defender was focused and/or made a play on the ball). These numbers differ tremendously and are considerably decrease than a defender’s true protection charge from 2019-2021, the place protection grades are given out to each participant on each play.

Taking a look at safeties, their uncooked protection charge falls in the midst of cornerbacks and linebackers, however they’ve the very best true protection charge. That is tremendously aided by the truth that safeties obtain essentially the most “zero” protection grades as a result of performs do not at all times attain them to power their involvement.
Cornerbacks have each the bottom uncooked protection charge and true protection charge, as they obtain essentially the most destructive grades out of any place. Since there’s a massive distinction between uncooked and true protection charges for causes beforehand highlighted, it requires us to make an adjusted protection charge for the seasons earlier than 2019.
Many extra elements assist create an adjusted protection charge for defenders, reminiscent of move breakups, targets, missed tackles, interceptions and common protection grades. These charges range tremendously by place, as proven within the desk under.

Since linebackers don’t play as a lot press protection, their pass-breakup charges are a lot decrease, however their common EPA allowed to offenses can be the bottom, which means they offer offenses essentially the most hassle in protection. Safeties have the very best charge of getting interceptions but additionally miss essentially the most tackles and permit essentially the most EPA to offenses, at 0.4 per play. As anticipated, cornerbacks are focused essentially the most, however they do break up passes essentially the most typically.
