To say that the Oakland Raiders struggled defensively in 2016 would be like reading an Andy Benoit quarterback breakdown and saying “Man, he really struggles with this, huh?”.
The unit’s woes were a major point of contention amongst fans and media alike from the very onset of the season, and blame for those issues bounced from scheme to coaching to the players themselves.
While opinions continue to differ as to what facet of the defensive corps deserves the lion’s share of this constant stream of castigation, fundamentally the answer is “all of the above”. Objectively, we can only speculate as to what players are coached to do and how well they’re coached to do it.
