That push came without the usual support of ACC Player of the Year and Tournament MVP J.J. Redick, who was held to a season low seven points on 1-of-7 shooting from the field.
Redick wasn't the only Blue Devil struggling with his offense, as only senior Daniel Ewing joined Williams in double figures with 14 points. As a team Duke shot just 41% from the field, and just 6-of-20 from the perimeter.
If Duke was bad, then the Hornets were just awful after intermission, missing 16 straight shots as Duke built their lead.
After the Blue Devils pushed the lead to 20, Delaware State began chipping away at the lead. After cutting it to 12 the Hornets' Troy Roundtree hit a fall-away three pointer and was fouled by Williams, sending him to the line with a chance to cut the lead to eight with 1:43 remaining.
However the free throw didn't connect and Duke was able to run out the clock, advancing to the second round to face the winner of Stanford and Mississippi State.
