The defending national champion Duke Blue Devils lost senior captain Amile Jefferson to a foot fracture in early December, so coach Mike Krzyzewski been going with a six-man rotation for most of the season. Despite a 4-4 start in the ACC, the Blue Devils won 20-plus games for the 20th straight season and are back in the Big Dance yet again.
