From what I understand, the violation was not that he met with Herbstreit. The kid told the coaches that he wanted to go to see the Gameday event. One of the assitant coaches took the kid to the site, but went further in that he got the player access to actually go on the set. The violation was that he was taken onto the set of Gameday - something that the average person doesn't have access to do. I very well could have heard this incorrectly, but that is what I heard explained on ESPN.
