Just playing with some numbers, I found that on-roster 3-star count was pretty strongly correlated with regular-season wins for SEC teams in 2019. I’ve done this in the past, and found that it is a pretty consistent relationship.
The correlation is 84%, R-squared is 70%, p-value is <.001, and SE is 1.76. Definitely something to this. The relationship between 3-stars and wins is strong than Blue-Chip count and wins, though it is close. This might just be a slightly different way of looking at the same thing, but I found it interesting.
