Mike Krzyzewski drew a circle around the basket on his chalkboard at halftime to make his point: Clemson was dominating that part of the floor, but Duke was in control everywhere else.
The No. 7 Blue Devils overcame their decided size disadvantage with quickness, using 24 points from DeMarcus Nelson to beat No. 24 Clemson 93-80 Saturday night for their 22nd straight win in the series.
"They just owned the boards," Krzyzewski said. "We were dominating the other part of the court, and they were dominating (the low post), but they're dominating it so much that if we continue, it won't make any difference what we do on the other part of the court. ... Our defense saved us."
Kyle Singler added 17 points and helped key the game-breaking run for the Blue Devils (15-1, 3-0 Atlantic Coast Conference). They blew a 12-point first-half lead, regrouped and eventually ran away from the Tigers while improving to 54-4 against them at Cameron Indoor Stadium.
