I need to start tracking the defensive stuff he does. It is subtle but I was really watching how he bothers guys shots and it was astounding. The only one not frustrated was that Williams guy. I put -20 as just a spitball round number but it might be more.
Korver is interesting to me. Defensively he really is a hole at times. He lets things in and has bad fouls. Yet he opens up offense for everyone the entire time he is on the court. His movement off screens is scary fast with that release.
