I imagine that a number of Duke fans enjoyed watching ACC rival Virginia struggle against 16 seed Gardner Webb earlier. They may not like it as much now.
Through one half, the Blue Devils are getting all they can handle from North Dakota State. Duke's defense looks good, but the the team is struggling to get things going against the Bison on the other end.
At the half, Duke leads 31-27. They finally took the lead at the nine minute mark with a Zion Williamson dunk, but have not run away with things.
Zion Williamson and R.J. Barrett have 10 point each for Duke, while NDSU's Vinnie Shahid leads all scorers with 15.
ESPN's Basketball Power index gives the Blue Devils a 95-percent chance to win, despite a tight margin.
Still, no one on Duke's side can be happy with the first half. At the half, Mike Krzyzewski said that the team "dug itself a hole," and was critical of his players settling for jump shots.
Obviously Duke has never lost as a No. 1 seed. That has only happened once: last year's Virginia loss to UMBC. The Blue Devils have suffered some bad upsets though.
In 2012, as a No. 2, Duke fell to C.J. McCollum and No. 15 Lehigh. Two years later, a three-seed Blue Devils squad fell to No. 14 Mercer.
Still, this would be another level, given Duke's talent and status as a heavy tournament favorite.
