This is the second part of my skilled rebounding study, this time with a focus on Defensive Rebounding. The full methodology is explained here, on the Offensive Rebounding article I last published. I know, I'm lazy, I don't want to go through it again.
The only change was converting the expected Offensive Rebounding Percentages into expected Defensive Rebounding Percentages, which was done by subtracting the ORB% from 100, to get DRB%. The breakdown is below.

Remember, the process is actual rebounds (DRR) minus expected rebounds (XDRR), equals skilled rebounding (XDRD).
DRR=Defensive Rebounding Rate
XDRR=Expected Defensive Rebounding Rate
XDRD=Expected Defensive Rebounding Difference
DRR=Defensive Rebounding Rate
XDRR=Expected Defensive Rebounding Rate
XDRD=Expected Defensive Rebounding Difference
- Normal DRR had a +8.51% correlation with wins in 2013. The calculated XDRR had a -1.61% correlation, and the "skilled" XDRD had a +15.4% correlation.
- The Thunder, Heat, Bucks, and Blazers were all below average in terms of traditional DRR, but based on where their opponents shot from, they were actually above average rebounding teams.
- The Wizards, Bulls, Wolves, and Clippers were all above average in terms of traditional DRR, but based on where their opponents shot from, they were actually below average rebounding teams.
That's all for now. I'm working on some cool ideas for rating a players "value" to his team, as well as messing around with the new SportsVu stats at NBA.com. I'll tabulate the "skilled" Total Rebounding Rates for 2012-2013, and post them on a tab at the left, along with the previous Offensive/Defensive Rebounding components.
