The recruiting rankings average over the last 5 years was pretty accurate in predicting which teams would have the most B12 wins, overall wins, 10+ win seasons, top 25 finishes, and top 15 finishes. Didn't want to spend the time to do the research but I would assume the other P5 conference show results similar to the Big 12 as well.
I used the last 3 years because 2017 was first year TCU/WVU had B12 recruited upperclassmen heavy teams.
