NFL Offseason - Over the past two weeks, we have looked at both YAC+ and our plus/minus stats from an offensive point of view, highlighting Deebo Samuel and Cooper Kupp and Kyler Murray and the best players in the passing game.

Do better pass defenses produce lower CPOEs above and beyond their control over where the ball is thrown?
