Playing as a top-ranked team for the 210th time under Mike Krzyzewski — but the first since February 2011 — they posted two key season highs, shooting 56.7 percent and forcing 26 turnovers, while holding the Big Red scoreless for an 8-minute stretch when the game got away from them.
Shonn Miller had 14 points to lead Cornell (4-7). The Big Red missed their first 10 shots of the second half and shot 22.6 percent over the final 20 minutes to lose their third in four games and falling to 0-4 all-time against No. 1 teams.
Cornell hung around for about 15 minutes before the Blue Devils pulled away at the end of the first half and turned the second half into one 20-minute-long run by outscoring the Big Red 47-17 to claim their 99th straight nonconference victory at Cameron Indoor Stadium.
They can extend that streak to triple digits Thursday night when Elon visits.
Once Duke — playing its first game since Dec. 8 and just its third this month — finally found its rhythm, several players put up some big numbers in the final box.
Curry was 7 of 10 with three 3-pointers in his second straight 20-point game and fourth of the season. Plumlee finished one rebound shy of his fourth straight double-double and was perfect from the field, hitting all eight of his shots at Duke's basket and one inadvertent and inconsequential one into the Big Red's.
And Cook, who has taken ownership of the starting point guard job during the past month, did all the little things for the Blue Devils. He finished the first half one assist shy of his previous career high of nine.
His pinpoint passing set up Duke's first three baskets out of the halftime break, when the Blue Devils built upon their lead by scoring the first 19 points of the half. Sulaimon pushed the lead into the 20s for the first time when his free throw with 16:51 left made it 50-30, and Josh Hairston made it a 30-point game with a three-point play that put Duke up 60-30 with 13:51 to go.
That lopsided margin made it easy to forget that the Blue Devils had trouble finding a rhythm until the end of a disjointed first half in which they shot nearly 59 percent, forced 15 turnovers — yet only led 41-30 after a 13-4 run that closed the half. Plumlee capped it with a layup with about 9 seconds left that gave Duke its first double-figure lead — and it only swelled from there.
