[The correlation between the 2-year recruiting rankings I used for 2018 S&P+ projections and the current year-end 2018 S&P+ rankings was a solid 0.609. That’s a strong correlation, and it’s why I use recruiting rankings in my projections.]
That's not that solid of a correlation. It's the type of correlation that someone that's used to seeing high-variance data jumps at but it's not all that meaningful when considering countable data.
I'd call that a moderate positive relationship. It's also super highly susceptible to another confounding variable. i.e. good coaches tend to attract good recruits and tend to perform better in S&P while the inverse is also true.
If you tested this against the 20% of winning-est coaches you'd probably find a much stronger causal relationship. Surprise! Good coaches win and have good S&P and attract good recruits!
This is where he completely lost me.
[The correlation between these new Pareto recruiting rankings and 2018 S&P+: 0.640. Better.]
Difference of .031 of .609 on an already moderate correlation? Probably statistically meaningless.

S&P: 91st.
LOL
87th in Pareto. 85th in 5 year percentile. 10th in the country.
Having Tedford back would be so fucking nice.
Take out the massively underachieving USC and FSU, and it rises to 0.661. Jerks.
Lulz

All of that said, Thanks for the FREE PUB!
