Analytics have been slow to come along with respect to football (compared to baseball, where Bill James was screaming about how dumb sacrifice bunts were back in the 1980s.) And compared to basketball, analytics have been much slower to be accepted in the football world. You can see that in the infrequency of fourth-down conversion attempts, in the face of evidence that over the long run going for it on fourth down will lead to more points scored.
That’s why SB Nation’s advanced statistical profiles are such a great resource. It doesn’t quite tell you everything you need to know about your team, but it’s still great.
