Strat-O-Matic Defensive Call - Playing Card Option
This is a method, using playing cards, to call a basic pass/run defense + time a quarter of play. The calls are pretty much based for use against an offense than ran 50%/50% run/pass. So, it should work ok against most teams. A few people have requested I upload to T-S, so here it is. Hope it is of some use to you. Follow this link to a you tube video which explains the basic way to use.
