Even a brain exposed to as much boron gas as mine already knew this was stupid. But now Five Thirty Eight comes out and debunks the value of NFL strength of schedule analysis. It's last year's data!!! Come ON!!! You can read the article here.
"... a better tactic is to make regressive predictions. We can use a regression formula to predict each team’s 2014 Simple Rating from its ratings over the previous two seasons, while building in plenty of regression to the mean to reflect our limited knowledge."

"In other words, the above SOS rankings are going to be wrong — but they’re almost certain to be a more accurate gauge of each team’s schedule difficulty in 2014 than the official rankings that only tap into last year’s records.
So, using 2 years of data is less wrong than 1 year of data, but it's still wrong. GAAAA!!!!
