Chris Carrawell and Shane Battier have been at Duke long enough to know the young Blue Devils aren't playing like former teams.
And after 19 years, coach Mike Krzyzewski knows it too.
"You could tell we weren't together out there. Duke teams in the past play hard every play. We aren't doing that right now," said Carrawell, a junior who led Duke with 20 points in a 99-52 win over Columbia on Tuesday night.
Duke (2-2), which has no seniors on its roster, lost to Stanford and Connecticut before beating Army 100-42 Sunday in its home opener.
Freshmen Carlos Boozer and Mike Dunleavy each scored 16 points while freshman Jason Williams scored 12 points and junior Nates James added 11 apiece for Duke.
"We didn't put together the effort we wanted to," said Battier, a junior who scored 11 points. "It's difficult but it's what makes Duke Duke. If you go out and expect to play your best every time out you're going to make the habit of being precise."
Leading 19-11, Duke went on a 19-0 run as Dunleavy made two 3-pointers.
After taking a 55-19 lead at halftime, Duke went ahead 66-23 with 16:48 left following Nate James' one-handed dunk and Boozer's two-handed slam and follow-up basket.
Carrawell made two 3-pointers to give Duke a 76-33 lead with 13:22 left.
Reserve Ryan Caldbeck had a chance for the second game in a row to get Duke's total up to 100, but he missed one of two free throws with 11 seconds remaining.
Krzyzewski said in other years the older Blue Devil have been able to mentor the young players and teach them the Duke way. But that's hard with seven freshmen.
"What's going to take awhile is the fact that we don't have as many upper classmen teaching younger kids," he said. "And that has been a big part of our system here at Duke. Not that Shane and Chris aren't trying."
The Blue Devils were able to carry on one tradition. The win was Duke's 38th straight at home and tied an Atlantic Coast Conference record held by North Carolina State, whose streak lasted from 1971-74 in Reynolds Coliseum. The Blue Devils' last loss at home was to Wake Forest on Jan. 11, 1997.
