Slightly off-topic, but I must say - I miss that harassing defense that Posey played on folks. Look at what he did to Kobe there in the youtube vid. He got called for a foul, sure, but then he proceeds to "foul Kobe again", right after the whistle. He was known for that, too.
Hopefully, Delonte, Marquis or Bradley can provide that kind of defense for us - up in your face - type.
