Nick Saban has hosted several NFL coaches this offseason as defenses learn how to best stop the zone-read offense.

The San Francisco 49ers, Washington Redskins and Seattle Seahawks all used elements of the zone-read last season.

Saban said the NFL is a pass rush-oriented league and that the zone-read sets up to exploit overpursuing defenses.

Saban also said that the 49ers have run the zone-read the best because of how they vary their looks so frequently.
