To stay qualified you have to show progress towards graduation, right? And the criteria are pretty lax. The NFL bound players only need three years, and they really don't need that. Stay eligible the first and second year, and part of the third, and bye. VERY few players these days turn up academically ineligible, I can't recall the last one of any note. It used to happen from time to time, some player would relax and miss the bowl game.
Now they have tutors staying on top of them ensuring they go to class at least. Tutors may also help "in other ways".
I would see lab reports come in identically copied from the same source with the same spelling errors, kids from the same fraternity. I took two to student court for cheating and they ruled I did not see them cheat.
