Answer the question AE87, which is more efficient. 70 points vs Elon and 10 points vs VT or 40 points vs Elon and 28 points vs VT assuming the same defensive output?
This post makes no sense. I've defined efficiency as points per drive and labeled points per game as a measure of productivity not efficiency. Therefore, I cannot answer the question as you have framed it.
The sophisticated opponent-adjusted measure of offensive efficiency from ESPN, OEPA (offensive extra points added), and my simple PPD statistic (supported for past years by the efficiency stat from footballoutsiders, FEI) agree that we are top 20 in efficiency. ESPN's OEPA says we're top 10.
Don't worry about figuring out my stat. If you think that we are not an efficient offense, please just provide the rational basis for why you think that.
