Back in late November we wrote about Duke’s historically bad defense. At the time, the Blue Devils were coming off their worst defensive effort of the last 12 years, having given up 90 points on 1.38 points per possession in their home squeaker against Vermont. Head coach Mike Krzyzewski was extremely upset and vowed that great improvement must be made on the defensive end of the floor. Five games later, it’s now a good time to see how much progress Duke’s defense has made in the intervening month of action.
Let’s take a more detailed look at the team’s defensive numbers from the first six Duke games through that dreadful Vermont performance on November 24. Then we will compare those statistics to what the Blue Devils have done in their last five games heading into the Christmas break. Here are the key defensive statistics from the first six games:
- 1.07 – Opponents’ Avg Points Per Possession for All Games
- 1.08 – Opponents’ Points Per Possession vs. Duke
By applying Ken Pomeroy’s principle of adjusting for competition, we come up with an Adjusted Defensive Rating of 1.05 PPP for Duke’s first six games. That number would currently put Duke’s defense at around #200 in the nation in Pomeroy’s ratings – lousy defense indeed. Now that’s look at the same metric for Duke’s last five games:
