DURHAM, N.C. Top-ranked Duke will have to be content to win with defense and an inside game for now.
The Blue Devils, struggling from the outside again, received 20 points from Carlos Boozer and forced 27 turnovers to beat Portland 104-62 Sunday night.
Boozer 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.
Casey Frandsen led Portland (1-2) with 28 points.
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 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.
The outside shooting and overall flow of the offense was so poor, coach Mike 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.
