The Blue Devils are the second-best team in the ACC and should be a top-two seed in the NCAA tournament.

But so far, they're responsible for the worst defensive-efficiency ranking of any Duke team in the kenpom era (2003-present), having dropped from fourth in '09-10 and eighth in '10-11 to 32nd this season.

Duke’s transition defense has dropped from 0.835 points per possession (which put them in the 95th percentile last year) to 1.000 points per possession (in the 64th percentile.

The Blue Devils’ defense on pick-and-roll ballhandlers has also dropped, falling from 0.638 points per possession (90th percentile) to 0.822 points per possession (28th percentile).
