I mentioned in my game recap of the Denver Nuggets 121-96 victory over the New Jersey Nets that Denver played very strong pick and roll defense. I purposely left the details out because I was planning on putting together some video evidence so here you go. Take note of how the Nuggets defended as a group and every movement was done deliberately with a purpose behind it.
The frustrating thing is watching them defend the pick and roll correctly it really is not that difficult. No one is doing anything superhuman or spectacular. To be fair, defending the pick and roll against Keyon Dooling is slightly easier than when Devin Harris has the ball, but the same principles apply no matter who is dribbling the ball.
