My brother played baseball at a state university. Not gonna say which one, but he took em to their first world series win.
In college he rarely went to class. He had tutors do that for him. In fact I know he passed courses he didn't even know he took.
The tutors would meet with him and teach him only what he needed to know to pass the tests.
They'd write his papers for him and call them "notes".
He had to sign with the pros after his junior year because he kept forgetting to show up for mid-terms and finals and despite all their efforts, he lost his academic eligibility. Not an easy thing to do back then.
It was much dirtier back then.
Those same things would be much more difficult to get away with today, unless the university is part of the SEC
