DURHAM, N.C. -- The flashes of brilliance have given way to consistent excellence for Carlos Boozer in the early going this season.
Boozer scored all 22 of his points in the first half on 10-for-12 shooting as No. 2 Duke rolled over Army 91-48 Saturday night.
"This shows that Carlos is a much different player for us," Shane Battier said of the 6-foot-9 sophomore. "He is playing big for us. His playing well so early tonight let us build off of him."
Duke has spent more weeks at No. 1 in the last decade than any other school. The undefeated Blue Devils appear headed there again.
The lopsided win, coupled with a 72-69 loss by top-ranked Arizona against Purdue earlier in the day, should land the Blue Devils (5-0) the No. 1 spot in The Associated Press poll next week for the 41st time since 1990.
"This is probably the umpteenth time I've been No. 1 since I've been here so it's no different," Battier said. "The second we put on a Duke uniform we know we have a bull's-eye, no matter where we're ranked."
Nate James added 12 points for Duke, while Jason Williams and Nick Horvath had 10 each.
Kenny Doleac led Army (2-1), which shot 29 percent, with eight points.
"We played against probably the best competition we will face all year," Army coach Pat Harris said.
Duke arrived on campus at 3:30 a.m. after edging Temple 63-61 to win the Preseason NIT championship on Friday night in New York. But the Blue Devils showed no signs of fatigue, making 10 of their first 11 shots.
Boozer, who scored 26 in the title game against the Owls, was the main target inside, making his first six shots as Duke built a 24-9 lead seven minutes in.
"We went inside in the first half and we're just a lot bigger than they are," Duke coach Mike Krzyzewski said. "We should score and we did.
"I was really pleased with Carlos because he built on last night," Krzyzewski added. "He should come out and dominate in a game like this. But some people should and they don't. He came ready to play and it was obvious our guys were looking for him."
The Black Knights were attempting to start 3-0 for the first time since 1980-81, but went eight minutes with only two buckets as Duke's 25-4 run salted it away.
Duke's 67-26 halftime lead tied for the third most points and third biggest margin in school history at the break.
Nine different players scored for Duke in the opening 20 minutes as the Blue Devils shot 71.1 percent and forced Army into 13 turnovers.
"When we were fast-breaking I know they're not accustomed to that speed," Krzyzewski said.
Krzyzewski rested his starters for most of the second half as the Blue Devils prepared to play No. 8 Illinois on Tuesday night in the ACC-Big Ten Challenge. Duke also has a rematch with Temple in seven days.
"It's an exciting week. This is why we come to Duke, to play the tough teams," Battier said. "Illinois is playing as well as anyone right now."
Krzyzewski said he was looking for effort and hard play from his team in its third game in four days. He liked what he saw.
"We kind of set this thing up to make it a tough two weeks for our basketball team," Krzyzewski said. "Not to do them any favors. These next two games will be difficult and we'll get better."
Duke beat Army 100-38 and 100-42 the last two times the Black Knights played in Cameron Indoor Stadium.
