Just think of it this way-- if colleges had the same standards across the boards regardless of legacy and athletics, March Madness would be filled with lower tier schools and community colleges-- no Duke, no Clemson, n0 whatever school. A question that most are not asking is why does USC need a champion crew/rowing team? Or, tennis team? None, if any of these students, are going to become professional tennis players at this point in their development. Why does the water polo team need to be part of a rubric that accepts lower performing students? This is why the side door was able to be opened by Singer. Yes, there are students who play these sports in order to gain a lower academic admit. Now one could argue that these students spent lots of time on these sports and maybe their grades suffered so why not give them an edge. But, let's be honest, colleges know they would have to give up the bye they give their basketball, football and track/field scholar/athletes for lowered standards if they let go of the scholar/athlete favored status for less competitive sports. This is a discussion that all in the higher ed field should be having. Not too long ago the NCAA had to raise its minimum GPA for acceptances and hold colleges accountable to ensure that a D1 football/basketball/whatever player actually could get a degree (and not just a recreation science degree) within a six year period.
In this scandal, yes, the parents (and the students in some cases) are cheaters and lack a moral sensibility that deserves a consequence-- legal and academic. However, the colleges made the scheme of a side door option possible and it was only a matter of time that the already corrupt system (lower performing students with different admissions guideline) was one that could be gamed by a shrewd huckster. I agree there are other aspects of this that need examination. If we allow everyone to focus on just this type of system gaming, I am confident we will miss the other potential scandals that are out there.
Fair disclosure: I was a college soccer player (D3) and gave up the option at a D1 school based on 4 and 6 year graduation rates of the team.
