DURHAM - Defense wasn’t supposed to be a strength of this No. 1-ranked Duke basketball team.

Coach Mike Krzyzewski said during the preseason that the Blue Devils would spend a lot of practice time focusing on defensive skills and habits.

In Duke’s first two games, though, defense has carried a Blue Devils team that has stumbled at times on offense. Duke held Miami (Ohio) to 33.3 percent from the field Tuesday night in a 79-45 win at Cameron Indoor Stadium.
