A night arranged to honor Mike Krzyzewski led to a two-way performance that surely made the legendary coach proud.No. 4 Duke visited the U.S. Military Academy in West Point, N.Y., on Veterans Day and beat Army 114-59, with Krzyzewski on hand to take in the game between his alma mater and the school he coached to five national titles.It was far from a mere exhibition for the Blue Devils (3-0). They’ll hope to carry their workmanlike effort into their next game Friday night against Indiana State in Durham, N.C.”For us to do this on Veterans Day was incredibly meaningful, especially to share this with Coach K and our players,” Duke coach Jon Scheyer said postgame. “They don’t get a lot of time to be around him. For Coach K to share in it with our players was very meaningful for me.”Then, I thought it was just a very business-like approach (Tuesday). They obviously played (hard). They did a great job sharing the ball. I thought just our commitment to defend, rebound and share the ball was what stood out for me.”Five Duke players scored at least 15 points, led by Dame Sarr’s 19 on 6-of-8 shooting from the field. The Italian freshman had a standout game after totaling just 10 points in his first two outings, and he added three steals.”I think last game I wasn’t so aggressive on defense. After talking with the coaches, that’s not who I am,” Sarr said. “So (Tuesday), I just wanted to bring myself, be aggressive on defense, and everything else came together. Whenever I’m focused on defense, then everything else comes by itself.”Duke’s defense has been outstanding through three games. The Blue Devils rank sixth in Division I in field-goal percentage allowed (31.2) and have kept Texas, Western Carolina and Army to 60 points or less.
