I was looking at Hollinger's team stats for last season and found this to be interesting. I took his offensive efficiency (points scored per 100 possessions) and defensive efficiency (points allowed per 100 possessions) data, calculated the difference and then ordered the 30 teams by the margin and this is the result:
This net efficiency rating seems like it was a pretty good predictor of team success. To nobody's surprise, the Blazers are near the top in offensive efficiency, but need to improve defensively to have a real shot at a title. They don't need to become a top defensive team, simply drop the points allowed by 3-4 per 100 possessions.
I think that adding Kaman will really stiffen the second unit, but it's clear that there's going to need to be a better buy-in by everybody to defense and that the younger guys simply have to get better.
