There's only one undefeated basketball team left in Division I — and it's the Duke women.

The fourth-ranked Blue Devils (15-0, 5-0 Atlantic Coast Conference) not only haven't lost, they haven't really been tested for a full 40 minutes.

Duke hasn't had a game decided by fewer than 10 points and its average margin of victory is more than 30 points.

If the Blue Devils get past Virginia Tech as expected on Wednesday night, they'll be in a familiar position — bringing a perfect record to Connecticut to face a highly ranked Huskies team.

Two years ago, Duke was the last unbeaten women's team at 20-0 entering its visit to UConn and wound up losing by 36 points.
