The Blue Devils took on the Black Knights of Army Friday night – the last tuneup before facing their first ranked foe of the season. Army provided Duke with a unique defensive look with their pack-line defense but they mixed it, going zone on occasion and others using a box and 1. The different looks were effective for spurts in the first half but the Blue Devils got plenty of open looks in the first half that just didn’t go down. Duke ended up shooting just 7-22 in the first half from beyond the arc but on the strength of their defense Duke was able to build a 23 point lead before the break.
