I'm really just looking for a more systematic way to playcall. I know Single wing, Wing t, ect teams run these types offenses. From what I understand they mainly look at who is making the play on defense and where. For example if the saftey makes the play for a 7 yrd gain they may run the same thing again. However, if the safety makes the play for 2-3 yrd gain they would run a complimentary play that looks similar but attacks the safety. Is this correct? Also, can you use this concept in other offense on a more general level without having to specifically see if a de is crashing or playing up the field, ect(since we can't really see these things in the game). I'm thinking something like this Also, can you take this concept and I apply it to defense ? At 12:17 he said something that stuck with me. The purpose of your base defense is to show them one look, see how they attack it, then make adjustments. To me this seems similair to series based playcalling on a larger scale and obviously from a defensive perspective. Is my thinking correct?
