Hubie Brown tells a story about how while coaching the Kentucky Colonels to a championship one of the plays he ran late in the deciding game he got from a the guy who coached his kid's freshman team. It all seemed a bit of a myth, but when Hubie went back to Memphis to coach there was a TV spot where Hubie gave the guy tickets and the guy recounted Hubie approaching him after a game and asking him about the play. As I recall Hubie telling us it involved using one of the positions in a way he had never thought of, thus being unexpected by his opponents. The point is a good coach can get ideas from anybody and has to choose what to do in the end.
