Last April, Duke, Wisconsin, Kentucky and Michigan State met at the Final Four to settle the small matter of a national championship. Three of those teams (the Blue Devils, the Badgers and the Wildcats) ranked No. 1 in their respective conferences in terms of points scored per possession in league play, and by the time we got to the national title game between Mike Krzyzewski and Bo Ryan you could make a good case that the last survivors featured the two best offenses in the country.
