I don't know much about why this had to be dealt with in this fashion at this moment, but I'd bet money this isn't the final say in this matter.
In a year or two the NCAA will self-reportedly do it's "due diligence" and allow these camps, with restrictions and regulation. They felt forced to close the loophole as it existed currently because it was starting to get out of control with Harbaugh scheduling 30 of these and everyone trying to keep up in a wild wild west type of scenario.
The NCAA is still full of sh#t, but I can at least partially understand why, for the time being, they got rid of all this.
