One of the most telling stats for coverage defenders at the NFL level is yards allowed per coverage snap played. Thanks to NFL Pro, Next Gen Stats’ data, built off of player tracking data, now allows us to sift through that information on a positional level, meaning being able to split players up by whether they lined up as an outside cornerback, slot cornerback or safety on a given play.
According to NFL Pro, the Green Bay Packers’ Xavier McKinney has played 65 snaps at a safety depth this season. Over those snaps, he hasn’t allowed a single yard as the nearest defender on a completed pass.
