LOL. Stop it. As Fry said, he asked a rhetorical question. He didn't want an actual answer with facts and math. Seriously.
Look, I will concede this much ground to Fry. I suspect that the further you get away from the top schools, the less predictive recruiting is. But, that is sort of like saying that beyond Alabama, Clemson, OSU, and Oklahoma, its a crapshoot on who else might make the playoffs. College football is top heavy, and the rich are always going to rake in the top talent and compete for a title every year. This aint the NFL with its socialistic rules.
But even then, there is a statistically significant correlation between rankings and wins and it is across the board, not just at the top. If not, that scatter shot diagram would just be a screen full of random dots, and not a regression line as it presents.
Anecdotally, most of us know that the math is backed up by common sense. While Iowa and NW and Wisconsin overachieve their talent due to great coaching, and Texas and UCLA underachieve their talent for opposite reasons, for the most part, we see a pretty decent relationship between where you land in the recruiting rankings and where you land in the final rankings.
Que Fry disavowing math.....
