It's about a book for sale, but to me, it's pretty interesting clicking on the chapter previews ...
I thought it was funny that the quote mentioned Don Chaney!
Chapter 17: Individual Defensive Ratings
Defense is the most difficult asset to measure in a player. Here is what we can do, what we’re building, and the problems that will continue into the future.
Quote: "If positional matchups are important, it is coaches that are critical in making decisions about those matchups. A good example is Dumars. Dumars' defensive rating was bad as a rookie then got better, which is what you'd hope. Then around 1993, Detroit's first year without Coach Chuck Daly, his defensive rating got really bad. I doubt that Daly's replacements, Ron Rothstein and Don Chaney, used Dumars at power forward or something crazy like that, but Dumars' defense became much less effective when they were around."
