I think you're missing something important here, or maybe you're just ignoring it altogether so you can weave whatever plot you need to in your mind. Roy Williams didn't think the class was fake. The students didn't think this class was fake. Easy? Sure. Fake? No. In fact they weren't fake at all, they were real. But was the class worth any credits, i.e. did it deserve accreditation? I would say that it didn't, given the way it was graded. However, to suggest that students or coaches should be responsible for vetting these courses for accreditation purposes is silly. You know what seems to be lost on you is the fact that the university self-reported this incident. I would say, initially that there was a lack of institutional control that allowed this course to be offered in the first place. But again, this isn't the students or coaches fault. In any case this will be my last statement on the matter until we find out what punishment the NCAA decides to hand out.
If Roy knew about it, I'd be worried. And again, the Syracuse case and this one aren't similar. Syracuse was cited as having members of the basketball staff actually DO the school work for the players. Not the case with UNC. Syracuse (namely Stan Kissel) tried to have one of Melo's grade's changed from the previous year in order to make him eligible. UNC never tried altering grades. I could go on and on. The point being that you have to look at each case individually, there is no blanket punishment. Look, I know you're dying for UNC to have to forfeit wins or even championship's in men's basketball...not going to happen. And it shouldn't.
I highly doubt the basketball department has to worry about anything coming out of this. Mainly because of the reasons already stated here and in all the reports. Bottom line is that Roy Williams didn't know there was anything wrong with this class, it's not his job to know...if it's being offered by the school why would Roy think anything was wrong with it? Half you guys probably think Roy came up with this class himself...or at least hope he did.
And that STILL doesn't implicate Williams. Look, in the end, what we have here is a paper class. A class that Mr. Walden and other athletic academic adviser's saw as an easy way for students to make a good grade. Mr. Walden didn't provide accreditation for this course nor any of the other adviser's. Walden and other athletic academic adviser's were simply doing their job. It's just stupid to compare something like this to blatant disregard for NCAA bylaw's such as the Ohio State case.
Ohio State players accepted money and other things in exchange for jersey's and rings while the coach knew about it. They KNEW it was wrong and did it anyway and got caught. Some UNC players may have taken an AFAM class that has since garnered criticism regarding the legitimacy of this course. It is not the student's job to question the validity of the classes being offered, they sign up and take them. (And btw, there has been NO proof that Roy steered any of his players to take these classes.) If anyone is at fault in the UNC scandal, it begins with the accreditation of the university, not the student athletes or the coaches.
