I should also add that whoever is covering a receiver (could be a CB, safety, or LB), must be 5 yards off the receiver at the start of the play. They can go forward and bullrush them, but there has to be space to start with.
Safeties are allowed to blitz once a quarter. I usually do this as a run blitz when a team is struggling to contain a running back. When a pitch/handoff is done on a board stoppage, all unengaged defenders can be turned. If a RB gets it "off the break," the board is stopped when he hits the line of scrimmage, and all unengaged defenders are turned.
On completed passes, the defense gets a 1-, 2-, or 3-second run to the receiver following the catch depending on pass length, then if there's no tackle, the receiver is pivoted, the defenders are pivoted again, and off they go.
So the defense gets plenty of love in my rules set.
