We recently posted a new article on our main site diagramming a 30 Front Zone Blitz with a Cover 4 (quarter, quarter, half's) versus a 2x2 shot gun spread offense.
This is a nice scheme when the defense has the offense in a throwing situation (needing 7 yards or more for a first down).

Keep spreading e'm!
