CHARLOTTE—Over the course of No. 1 Duke’s undefeated run through nonconference play, head coach Mike Krzyzewski hasn’t seen much—anything, really—from his team that has upset him.

And even though Duke’s 67-50 win over Davidson was a struggle for the majority of the game, Krzyzewski came into the postgame locker room in a good mood, cracking a joke about the long walk he had from the Blue Devils’ locker room.

And, while he said he was pleased with his team’s performance throughout the game, he succinctly summarized the difference between the first half, which ended in a 29-29 tie, and the second.

“In the first half, we gave up offensive rebounds,” Krzyzewski said. “In the second half, we didn’t.”
