WTF Happened?

So if you've been checking the blog recently you'll know that I recently went on a cruise. I am also a HUGE college basketball fan (GO VCU and UNC!) When I left Jan.3rd North Carolina was 14-0 and heading into ACC games.
I get back and the week that I missed can be summerized like this:
They got punched in the face, went 1-2 overall and 0-2 in the ACC! They won the other night to stop from going 0-3 in the ACC, my question is what happened?
I've concluded that since I was out of the country UNC felt that they had no one to impress...well I'm back and puttin them on notice, get your shit right.
