One thing we do, its not new, I started it 3 years ago. We put together a play sheet of different situations and do a live defense time period. It has the same concept as 21 outs but it is like a 21 outs on steroids. I believe there are like 56 plays. We keep track of positives and negatives on each play. Defensive unit has to record a 80% success rate each day or they run a triangle. We do it for 15 minutes and incorporate JV for live runners.
