I know that athletes get admitted who otherwise would have no chance, whatever the school (almost).
I think the same may be true for music majors or art majors at times.
HS athletes feel that they can get by in HS because the fix in in, often as not. Even if they realize belatedly that they need some grades to get into college (and SATs), they can't catch up in two years very well. So maybe they slide in to some football school and then get sheltered there with tutors and of course a planned pathway of coursework that is easy.
For some reason, when I was at UGA Geology was one of the science courses considered to be easy, and the nickname was "Rocks for Jocks".
We pretty much knew the "crip courses" that could up your GPA with ease. I took a couple of them.
