The way I had it explained to me was that now every school is abiding by the rules that the SEC has had for a few years. Backcounting, blue shirts and grey shirts are all still possible. So signing over 25 can happen.
Yes, I was being sarcastic. The teams I listed are teams that somehow seem to get away with shady things at times. Like Miami getting totally off the hook a few years ago after being nailed to the wall.
