Duke Basketball: Blue Devils' Biggest Concerns Ahead of Conference Play

Duke comes back from a nine-day hiatus when it hosts Georgia Southern on Tuesday. It's one of just four games remaining for the Blue Devils before the calendar switches to 2016 and the schedule moves from nonconference action to ACC play.
