Just as an example if we're on the same page.I can't recall the UA admin going to Saban and telling him he can't sign a guy for other reasons though, which has been the case with ND and Kelly numerous times.
One of the requirements at ND right now is an essay on a quote from one of the founders of a Congregation. The subject matter is on a higher plane than an essay in Comp 101 but I don't see it as difficult as the requirements for say New College at UA. (That was a bitch to write.) At ND it's basically labeled as "let us get to know you better" through this excercise.
Is this something you're calling "other reasons?" IE: an athletes answer and whether or not they fit with the ND "culture."
If we're on the same page, these "other reasons" apply to BYU as well, right? I'd certainly think there would be an issue with a QB out of Provo whose parent own a local pub.
