"A Duke team should play with energy for 40 minutes, or 45," Krzyzewski said. "Go outside right now and you look at the banners. There are quite a few of them up there. They were not won without energy, without hunger, with complacency, with people really wanting it.
"And we've wanted it a lot, and we've won a lot. We're supposed to play hard and with energy all the time. Those are givens. Those should be givens."
Instead, the Blue Devils (19-4, 6-2 ACC) have lost two of their last three games at Cameron Indoor Stadium and have dropped multiple home games for the first time since going 15-4 there in 2006-07. Krzyzewski compared his team's only home win in the past 2 weeks - a victory over St. John's - to an AAU game because of Duke's occasional lack of intensity.
Seth Curry scored 22 points and freshman Austin Rivers added 20 for Duke, which missed all six of its free throws in overtime and wound up being beaten at home by a Florida-based conference rival for the second time this season. Duke had its 45-game home winning streak snapped 2 weeks ago by No. 21 Florida State.
"To come in here and play with the kind of poise we did, play the kind of defense we did, especially in the first half and in the overtime, was something that we can be very, very proud of," Hurricanes coach Jim Larranaga said.
