Caltech, a technically-focused nerd-haven with ~900 undergrads occupying 2 city blocks in Pasadena (and my alma mater, hence the username) was hit with NCAA violations for a lack of institutional control (link below). Apparently, its because students, who have the first couple weeks of term to figure out their schedules, may not have been properly enrolled in the system and were thus ineligible. Of course the coaches, most of whom have other jobs cuz a coaching job at a D3 school doesn't pay a whole of scratch, had no clue about the foibles of the system, and didn't catch it. Of course we have little to no compliance staff either.
Speaking from first hand experience, the students are already wrecked from the demands of insane professors and a curriculum that has all grads (even english majors) study theoretical quantum mech and differential equations as sophomores. Sports are what kids do to get away from crushing amounts of work. I had buddies who would regularly run from preparing lab experiments to basketball or tennis practice, all after working back-to-back all nighters. I of course didn't play sports cuz we haven't had a football team since 1993. As far as trying to gain some competitive advantage, this is dumbest thing in the world, cuz our teams all suck ass.
This just might be more frivolous than practicegate (though nowhere as public). I figured that on a lazy Thursday, we could all have a good laugh at the NCAA and the things they waste money on.
I'd put the over/under on wins vacated at around 20. Across 13 sports. Over maybe 3 years.
