I have always been intrigued with Coach Woody Hayes. Although he is most remembered by an incident in a game, everyone said he was a tremendous teacher. I read once that he did a study on the geometry of the force created by the down block, in order to prove his logic. He took the math and applied it to football to make his teams much greater than his opponents. He solved for the "why", or in mathematical terms, the hidden variable "Y." Taking a page from option teams of the past, wide line splits are nothing new to football.
My favorite pass concept of the past five years has to be the Double Post concept. A well run post is one of the most difficult routes to cover, so my thought is why not run 2!? The Double Post concept is something that has been around the NFL and College for a long time. In the West Coast, it is run as a Dino Double Post and a wrinkle on it was made famous by Steve Spurrier and the Florida Gators.
