The have allowed the most explosive plays (29) by any team in the league through three weeks. Brandon Staley's defensive system, inspired by his mentor Vic Fangio, has come under some justified criticism after multiple years of being consistently below expectations despite having the most expensive defensive roster against the cap. The pass defense is the more concerning aspect of a system that has been designed to prioritize the air attack. With that in mind, I wanted to get to the tape and check whether the problems stopping big passing plays have been the scheme itself, the play-calling, or the player execution.
