If you have been reading my stats posts all season, you are know that the “success rate” and “EPA” are the base for a lot of the metrics that I break down. But, I’ve added a wrinkle to the metrics that may help bring home some of this “efficiency” talk.
EPA is a value based on a play’s result which is calculated from like a billion plays from college football. Success rate is a yes/no formula of a plays which gain 50% on yards to gain on 1st, 70% on 2nd, and 100% on 3rd and 4th downs.
