This is a great question and one that could be relatively easily answered by an enterprising individual with a bit of stats background.
You could take all the 5 stars at Bama and track how many get drafted, then do the same for 4 stars.
Then do this for the next 10 schools that dominate getting 5 stars over the past 10 years.
Off the cuff, I bet Bama, and Clemson maybe OSU do more with more and Miami, Texas, Tenn, Florida, Auburn, FSU etc do less with more and OU, Georgia, aTm do about average... again, all ’star rankings’ being equal.
My thinking is to be elite, you must recruit well(4/5 stars), but to be the elite of the elite, you must both recruit and develop
