Stop reading now if you have no interest in Offensive Efficiency metrics, this is a very TLDR post (
@IowaLawWasRight -esque)
Do you know how to tell someone has an agenda when evaluating Iowa's offense? Their go-to stat will be "yards/game."
With Iowa's style of play, which includes emphasizing time of possession (hence fewer overall possessions) and field position (hence ideally working with shorter fields), Iowa almost always does worse in yards/game than they do in the much more important metric of pts/game.
I was looking at data over the past 13 years (this is how far back "efficiency" metrics are available). Over that time, Iowa's national rank in pts/game is on average 16 places higher than its national rank in yards/game. Over the last 5 years (New-Kirk era), the pts/game national rank is on average 31 places higher than its national rank in yards/game.
So who loves to use yards/game? Nebraska fans. Because they can fools themselves into thinking that Frost is some kind of offensive wunderkind. Nebraska kind of stunk the joint up on offense this year, but they can still say, "We were 55th in yds/game, and Iowa was 99th." And they would be right. But what if we look at pts/game?
Nebraska was 72nd nationally in pts/game, Iowa was 89th (it was a terrible year for Iowa in the red-zone). So Nebbie still has the upper hand on that side of the ball. But, what about accounting for the fact that Nebraska has way more possessions based upon their style of play, and they turned the ball over like a sieve?
Well, to account for that, we need to look at Offensive Efficiency.
Football Outsider is a great resource to use for this. They essentially look at how many points a team gets out of each possession, adjusting for starting field position and quality of the opposing defense.
ESPN also has efficiency metrics, but they do not control for quality of opposing defenses.
If we look at Efficiency metrics, we see that Iowa outpaces Nebraska with a national ranking of 62nd vs. 80th (Football Outsiders) or 52nd vs. 67th (ESPN). Nebraska also ranked 96th in the country in turnovers per possession, Iowa ranked 28th.
Furthermore, we can see that the Nebraska fan-base's disdain for their D-coordinator is probably misplaced, as Nebraska's defensive efficiency was substantially better than their offensive efficiency (44th vs. 80th).
Don't get me wrong, in general it is better to have more yards than fewer yards, it's just that yards by themselves are so incomplete. On Iowa's schedule alone this year, the losing team out-gained the winning team 4 times (ISU, PSU, Minn, USC).
So hopefully we can catch up with basketball fans, who have long since eschewed pts/game for pts/possession metrics, and we can ditch "Yards/game" as a go-to metric to encapsulate offensive quality.
