Our high rebounding numbers are basically entirely a result of our offensive rebounds, we are 2nd in the league at corralling 29.5% of offensive boards second only to the funky lineup Pistons whom pull down 30.9%.
But for defensive rebounds we are right at the league average with 74.6% which is 16th. The Pacers are #1 at 77.0%, while the Spurs are 3rd at 76.4%. Both those teams are excellent defensive teams. There is a very high correlation between good defensive efficiency and good defensive team rebounding.
The big downside with our accomplishment is teams that get a large amount of offensive rebound are normally poor defensive teams since they don't get back on defense early and are out of position. The Timberwolves are the only team in the top5 of offensive rebounding with an above average defense, and I hate to think they are any sort of a model for us to emulate.
I am impressed that we are a middle of the pack defensive rebounding team, I was very concerned with starting bigman duo of Aldridge and Lopez but it has not been a weakness.
