I weighted the PA against the offensive ranks of our opponents. the 16th ranked offense gets a multiplier of 1, any rank better than 16 gets a multiplier of 0.95, 0.9, 0.85 etc.... any offense ranked worse than 16th, gets a multiplier of 1.05, 1.1, 1.15 etc...
So in this scenario, the 21 points we gave up to the texans in our win counted as 16.8 because they are the 12th best offense. the 38 we gave up to the patriots counts as only 17.1 as they are the 5th best. conversely, the 34 we gave up to Cincy is more Like 49.3 because they are ranked a lowly 25th.
So in this way, a PA against the worst offense counts as 1.8 PA... a PA against the best offense counts for 0.25
So our actual PA was 313
Our weighted PA was 390.05
the average rank of our opponent is 22.2
We've only beaten two teams in the top half. We had an easy schedule.
