These schools have teams, but they are not relying on them to get ad revenue, etc. Also, unlike big D1 athletic programs, they do not have staff around whose job is supporting these kids academically on the way to a bowl game.
What that means, in a real sense, is that any applicant needs to demonstrate an ability to handle the academics and thrive as a student as well as an athlete.
And while the system does allow coaches to select a part of every incoming class, provided that the applicants have cleared their bar, the admissions team is ultimately responsible to the school for creating a class that is what the institution wanted.
This is a long way of saying that it really depends on the sport, the school, and the kid but it’s highly unlikely that any school will go way outside the academic norms for any athlete.
