It is all relative to the era and the rules of that era. The increase in scoring of late is due to the exploitation of allowing lineman to be 3-5 yards down field by the RPO offenses. Even if 28 is the new 14, defense still decides championships.
As far as yards gained, the new strategy to combat the RPO I have noticed is to stuff the run with the front seven and the secondary playing contain. This leaves a soft spot for shorter routes.
This strategy will yield yards and TOP, its aim is to prevent RAK and deep explosive plays.
Once the field is shortened, the secondary presses the receivers more and tightens up.
