When Kentucky won the national championship in 2012 with a team built around Anthony Davis, Michael Kidd-Gilchrist and Terrence Jones, they finished the season with an efficiency differential of +24.8.
The Wildcats scored 114.4 points per 100 possessions while giving up just 89.5. Kentucky lost just two games that season (Indiana and Vanderbilt).
This season, John Calipari's team has an efficiency differential of +32.6. Kentucky is scoring 114.0 points per 100 possessions and have been even better on defense by allowing 81.4 points per 100 possessions.
Kentucky figures to play at least some closer games during the SEC Tournament and NCAA Tournament, which could reduce the efficiency differential, but it will likely remain significantly better than their very good 11-12 season.
