Could there be something here, probably not. Since compliance looked into it within 2 months of it happening, there's nothing to worry about. Just like the espn story says, if compliance looked into it and no players received any benefits plus added a cease and desist letter since the guy had the pics on his facebook page, there's nothing wrong. The only possible problem would be if some form of extra benefit actually was extended. Otherwise this just looks like a fan with a clothing store who displays memorabilia in the store... not that uncommon in a college town is it?
