@northwesty, the situations just are not analogous. In one situation, the athletic department actually decides which kids to admit. In the other, the athletic department gets some amorphous level of slack from the admissions department. Through my son’s, and a few of his former teammates experiences, I have pretty complete information about how recruiting works (at least for revenue sports) at the Ivys, NESCAC, Duke, Vandy, AIr Force, Navy, Army, ND, Michigan, Northwestern and Stanford. With the exception of Stanford and the service academies, all of the FBS schools guarantee admission to recruits (not only scholarship recruits but recruited walk ons). The military academies require higher initial standards and a character and fitness review, but operate the same way. Stanford is kind of half way between the AD controls admissions/NCAA eligibility standards schools and the Ivy/NESCAC “only admissions admits” model. Stanford requires a completed application and then requires recruits to go through an abbreviated admissions review, not dissimilar to a likely letter review, although anecdotally they have more elastic standards than the Ivys. How Stanford can compete at the top of D1 with that process is a mystery to me. I know for a fact they lost out on at least one 4 star guy in recent years because they could not guarantee admission without this admissions review, and the recruit and his family were concerned that if the recruit applied, word would get out to other high profile schools and offers would disappear, leaving him somewhat high and dry if he was declined by Stanford.
At its most basic, if a school like Vanderbilt, for example, operated similar to the Ivy, or NESCAC, then the football players at Vandy (as an example) would have to have academic numbers in the same ballpark as the general student body. Instead, because Vandy gives the AD control over a certain number of admission slots, the only requirement is that the recruit meets NCAA standards. It is a big difference. Since you have kids of dissimilar academic backgrounds and maybe skills, athletes tend to cluster to certain courses and majors, and require substantial tutoring help which not only is fertile ground for the type of thing we saw at NC, but leads to even more self segregation than is inherent in the difference between athletes and normal kids.
