The Duke Blue Devils (35-5, 13-3 ACC) are probably the best team in the ACC and they may also be the best in the nation. Last season, the Devils tied for first in the ACC and then went to the Big Dance where they won it all. You wouldn’t say last season that Duke was the best team in the country, but they proved to play the best when everything was on the line. It was a validation of sorts for their coach as in recent years Mike Krzyzewski’s teams had been knocked out of the NCAA Tournament in the early rounds. People were starting to wonder about the strength of the program. Now they’re wondering if the word “repeat” will be in their vocabulary this season.
