It worked very well, but it did have some issues: The new BPM was developed with these issues always in mind, with a goal of fully resolving the problems. As you mention, its extremely hard to evaluate defense with statistics, which complicates the problem. This also can be used on much smaller data samples and still produce realistic results. I'd almost given up on that website updating anytime this season. Watch our How-To Videos to Become a Stathead, Subscribe to Stathead and get access to more data than you can imagine. Defensive rebounds by guards mean almost nothing in this regression (in other words, the credit is split perfectly evenly to all 5 players).
