DURHAM, N.C. (AP)- Mike Krzyzewski wants togetherness right now more than 40-point wins.

And the Duke coach made a point to tell the Blue Devils just that following a 104-62 victory over Portland on Sunday night, spending 20 minutes with his team in the locker room after the lopsided game.

"Coach is a little upset," Mike Dunleavy said. "He expects a lot out of us. That Portland team played really together and played hard and he's trying to teach us to do that."

Krzyzewski wasn't pleased with Chris Duhon's play, so he was benched to start the second half. And at one point, he called a time out to yell at his team as they were lining up for a free throw.

"The game is not coached for just this game, it's to see different things," Krzyzewski said. "If you're trying to figure it out just for this game it's probably a square peg trying to be put in a circle."

The Blue Devils, struggling from the outside again, got 20 points from Carlos Boozer and forced 27 turnovers to beat Portland.

Boozer, 11-for-11 from the field in a 33-point win over the Pilots last season, made 8-of-14 this time and grabbed 13 rebounds as Duke (4-0) had six players score in double figures and won its 20th straight home opener.

Dahntay Jones added 17 points, while freshman Daniel Ewing had 15.

Jason Williams, Duke's All-American guard who was 0-for-5 from 3-point range and scored just 10 points, took Krzyzewski's postgame message to heart.

"We have to understand just because we're being hyped up as `The Team,' we still have a lot to work on," Williams said. "This year's team has to realize that we don't have anything. We have to have that hunger to go after it."

Casey Frandsen led Portland (1-2) with 28 points.

Duke shot 39 percent from 3-point range a season ago, but came in with the Pilots hitting 33 percent after three wins in the Maui Invitational. That number took a hit Sunday night as Duke missed 19 of its first 20 3-pointers and finished 5-for-25.

"We weren't as sharp as I would like us to be," Krzyzewski said. "I don't know if that's all the travel or what. We can talk about jet lag and all that stuff, but when you show up to play you need to play sharp."

The Blue Devils missed their first nine beyond the arc and finished the first half 1-for-15 as the Pilots, who lost in overtime to Idaho State four days ago, remained in it.

While Duke's offense struggled in steamy Cameron Indoor Stadium, its defense was super, forcing Portland into six straight turnovers to start the game and 13 for the opening 20 minutes to build a 16-point lead.

The outside shooting and overall flow of the offense was so poor, Krzyzewski dug deep into his bench to play Matt Christensen and walk-on Mark Causey to try to find a spark.

It worked as Duke went on a 10-0 run.

Dunleavy made a follow shot and hit the team's first 3-pointer with 5:06 left in the half, and Jones added a pair of driving layups for a 31-14 lead.

Dunleavy turned the ball over on Duke's first possession of the second half as Krzyzewski put his hands over his face, but a 20-2 run minutes later helped put the game out of reach.

Boozer sparked the surge with a three-point play, a layup, a bank shot and a free throw as the Blue Devils went away from jumpers to a running game that produced some easy buckets.

A pair of steals by Williams led to a fastbreak layup by the junior guard and a dunk by Dunleavy as Duke went up by 31 with 14:43 left and cruised from there.

"We're not making shots, but we're really not connecting," Dunleavy said. "A lot of them are good shots but you're got to be more into it, you're got to drive and kick the ball."
