Saban explained how the Tide's defense had three different play calls on each snap, and the defensive play would be called depending on Florida's formation and/or movement.

Most often, it's the offense that makes the pre-snap read of the defense before going into a play call.

But Saban's philosophy circumvents that offensive advantage and gives the defense an opportunity for the final say - excluding quick snaps, as the Oklahoma offense has proven it can easily do with its no-huddle..
