Let me weigh in for a sec. since I have a unique perspective here... I actually received my law degree from the evening program at NCCU (a program that was harder to get into, statistically, than Duke law...)
Ph is correct that all the snide comments about Duke athletes taking classes at NCCU certainly appear at least partially racially biased. But, I think there is a different explanation. I'm speaking for others here, but, I don't think people generally have a problem with the concept of Duke athletes taking classes somewhere else. The problem is the hypocrisy shown by the media coverage of Duke.
You don't hear it as much anymore, but, you used to hear Vitale and others talk about what a great school Duke is and how the Duke students are all so smart so Duke athletes are truly student athletes and isn't it amazing... blah, blah, blah. Like I said, you don't really hear it since Duke sold out to the one-and-done model but it used to really be nauseating. And it really becomes annoying to those who know the reality that the great majority of Duke basketball players (white and black - Laettner's SAT score was rumored to be a joke) could never get into Duke (not saying that it is not also that way at other places, including Wake - just that the media always acted like Duke was different) and likely couldn't handle the typical class load at Duke. So then when it became common knowledge that the Duke players took a lot of classes over at NCCU - presumably because they were easier (because why else would they take them, went the logic) - that became a talking point among the Duke haters.
I believe that is all that is going on and that it isn't really racially motivated. When I was at Wake I took summer school classes at App St. because they were laughingly easy - why wouldn't I fulfill basic requirements that way?
