DURHAM, N.C. -- Mike Krzyzewski knows No. 1 Duke doesn't always live up to expectations. That was the case Saturday.
The Blue Devils looked rusty after an 11-day layoff but got a career-high 25 points from Mike Dunleavy and 21 from Jason Williams in a 92-79 victory over San Diego State.
A late run by the Aztecs gave the unbeaten and defending national champion Blue Devils evidence that their play can improve.
"At times people think we're just going to roll over people and it's not going to happen -- at least not this team right now," Krzyzewski said.
Duke was up by 25 points in the second half before a 18-3 run by San Diego State made the score respectable.
The Blue Devils scored 90 or more points for the fourth straight game, but they allowed a season-high 53.2 percent shooting by the Aztecs, missed 14 foul shots and had 17 turnovers.
"We have to put the punch on teams when we've got them down by 20," said 1999 Juenau-Douglas High School graduate Carlos Boozer, who scored 14 points and grabbed five rebounds despite just playing just 21 minutes because of foul trouble. "We've got to finish off plays and we haven't done that to the extent that we're capable of doing."
Still, the Blue Devils (11-0), whose last game was a 95-92 overtime win against Kentucky on Dec. 18, remained one of five undefeated teams in the country. Their 21-game winning streak dating to last season ties the school's fourth-longest mark.
Randy Holcomb had 22 points and 15 rebounds for the Aztecs (7-4), while Tony Bland added 21 points.
"They gave us what we expected," Krzyzewski said. "They are an older team so they are going to look forward to playing against us, they're not going to be intimidated. This was a big thing for them and it should always be a big thing for us, too."
The last time San Diego State coach Steve Fisher was in Cameron Indoor Stadium was in December 1996, when his Michigan team beat the Blue Devils 62-61 on a last-second basket by Robert Traylor.
