In part one of this series, we covered the base 4-3 fronts fans can expect to see this coming season.
As the 49ers continue to build their defensive scheme in the mold of the 2012/2013 Seahawks, one thing fans can expect to see from the pass defense is the cover 3 and cover 1 defenses, a significant departure from the primarily cover 2 defense employed in the past.
Cover 3 is most basic pass defense at levels of football.

In cover 3, the outside corners and the free safety drop into coverages that divide the field into thirds, with the underneath linebackers dropping to the middle and flats to take away the intermediate passes.
