NCAA will have to change their by-laws for it not to be otherwise everyone will have to sue to get an injunction. This one is a lot murkier than the other lawsuits that have been happening. There's absolutely nothing saying a judge won't turn around and say "lol, no".
I've no doubt a bunch of unbelievably stupid players would waste two years of their time in JUCO and then attempt 4-5 in college but this isn't going to be some major thing regardless.
The bubble on this is going to pop. If you aren't blind you can see it ready to happen already. These kids haven't magically figured out how to beat the system, the system is just taking its time figuring out where on the players' neck they want to put their boot back down, same as it does with the rest of us.
