When Duke gets to the NCAA tournament, Coach K will be able to tell them truthfully that they've already had some tough turn-arounds. The NCAA might require Duke to play the first game Thursday night and then come back for the second round early on a Saturday afternoon. That's what the Tech/BC sequence is, and throw in the travel to Boston.
Just my guess, but I think Duke will be ready to play Saturday afternoon; the NC State and G-town games were bitter pills.
