Just saw this on the crawler while watching DC United vs. Seattle, and checked on ESPN to confirm.
Looks like UNC is being investigated for agents and other benefits. This is very preliminary by the sound of the article, but when you are interviewing players there definitely is some smoke. Knowing nothing about Butch Davis outside of the fact he built those crazy Miami teams and then failed in the pros, and the fact that he is pulling in great recruiting classes at a school not particularly known for its football exploits, it will be interesting how this plays out. Personally, I'm not that surprised that there are at least some whiffs of improprieties.
