DURHAM, N.C. -- A month ago, Mike Krzyzewski said No. 1 Duke could develop into the best passing team he's ever coached.
The coach had a much different view following a 104-62 victory over Portland on Sunday night, saying his team lacks cohesiveness and doesn't communicate well on the floor.
"If we win by 42 and guys are diving and guys are there to help each other out, not waving each other off or giving each other dirty looks, then it's a different win," Duke's All-American guard Jason Williams said.
"It's different because you feel you won together. Tonight, I feel like we just won apart. We just won our separate battles."
Krzyzewski didn't care that Duke (4-0) missed 19 of its first 20 3-pointers and ended 5-for-25 from beyond the arc to remain mediocre from long range after four games.
As usual, he wants his club to keep shooting if players are open.
But Krzyzewski also wants 1999 Juneau-Douglas High School graduate Carlos Boozer to be stronger inside, Williams to lead better and players to play for each other -- not as individuals.
"The best means to develop cohesiveness, to have great communication," Krzyzewski said. "More than anything we lost from last year was the best communicator to maybe ever play college basketball in Shane Battier.
"That is just something that needs to be worked on," the coach added. "We can't have it be the 1920s and have silent movies. We can't have closed caption. We have to talk more."
The Blue Devils, struggling from the outside again, got 20 points from 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 had six players score in double figures and won its 20th straight home opener.
But Krzyzewski was critical of his game.
"He didn't finish in the first half," Krzyzewski said of his junior center. "He's trying hard, but I think he played just all right."
Dahntay Jones added 17 points, while freshman Daniel Ewing had 15.
Casey Frandsen led Portland (1-2) with 28 points.
Duke shot 39 percent from 3-point range a season ago, but came in hitting 33 percent after three wins in the Maui Invitational. That number took a hit Sunday night as Duke was miserable from beyond the arc.
The Blue Devils missed their first nine long-range shots and finished the first half 1-for-15 as the Pilots, who lost in overtime to Idaho State four days ago, remained in the game.
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.
Mike 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.
No. 19 St. Joseph's 81, Colorado 75
In Philadelphia, Marvin O'Connor scored 29 points, shooting 5-of-8 from 3-point range in the second half, to lead St. Joseph's past Colorado.
Bill Phillips, 4-for-5 from behind the arc, added 18 points and seven rebounds for the Hawks (2-1).
St. Joseph's relied on O'Connor's shooting and aggressive man-to-man defense to deliver the first loss of the season to Colorado (3-1)
