After rolling to two exhibition victories against Division II schools by an average of 58.5 points, the Blue Devils were met with only slightly more resistance from a Presbyterian program entering its second season in Division I.
Duke -- which hasn't lost the first game at its notoriously noisy arena since 1982, and won its ninth straight season opener overall -- denied the Blue Hose (0-1) their first road victory in 24 tries at this level.
Duke controlled both ends of the court, holding the Blue Hose to 1-of-11 shooting during one early stretch before reeling off 19 straight points -- coming away with points on seven straight trips downcourt -- to take a 20-point lead. At one point late in the half, the Blue Hose had more than twice as many turnovers (11) as field goals (five).
It was precisely the kind of performance expected of a Blue Devils team that returns nine of the top 11 scorers from an offense that ranked fourth nationally last season by averaging 83.2 points.
"We're pleased to advance in the tournament," said Krzyzewski. "I thought our defense was excellent, and with our offense, a lot of it had to do with their defense. They played really hard. We can't commit 21 turnovers going forward, and miss some of the shots that we missed tonight."
Duke took the lead for good during the defense-dominated 13-2 run during which the Blue Devils allowed one basket during a 7½-minute stretch, a spurt capped by Greg Paulus' 3-pointer from the left wing that made it 13-4 with 12½ minutes before halftime.
Then, they gave themselves plenty of breathing room with the Smith- and Scheyer-keyed 19-0 run, a burst capped by Gerald Henderson's free throw with 3:51 left that made it 36-11. By that point, Scheyer had 12 points by himself, prompting those clever Cameron Crazies to chant, "Scheyer's winning."
"It didn't feel like a 19-0 run," said Scheyer. "It felt like we were just dragging a little bit in the first half with our offense and it wasn't like a typical run that we feel like we can have. We felt like it could've been a 30-0 run with the way we could've played. We just didn't make those plays and we usually do."
Al'Lonzo Coleman finished with 13 points to lead Presbyterian, and his layup 17 seconds in gave the Blue Hose their only lead. Freshman Bo King also had 13 points on 3-of-15 shooting.
Presbyterian will play Houston on Tuesday in a consolation game.
