Look out, Duke: Here comes UNC

Here at Poll Position, I'm not in the habit of touting teams that lose by 20 at Georgia Tech. But what North Carolina has done in the five games since that loss merits some ink. I guarantee you those five games have Mike Krzyzewski's attention as he prepares his Duke Blue Devils for a visit from the Tar Heels on Wednesday night.

Two weeks ago, the consensus was that no opponent could give Coach K's team a run for its money in the ACC, but it turns out that writing off the rest of the conference was a little premature. Roy Williams' team suddenly looks a lot like, well, a Roy Williams team. For the first time since Tyler Hansbrough and Ty Lawson were sprinting up and down the floor in Chapel Hill, UNC is again scoring points. A lot of points.

What changed?
