Query: A good video for average to good players.

I had been looking for a video to help teach my son, who is an above average player. Not finding much on defense, I decided to try this video. It was very good. It had a lot of skating drills geared toward defensemen. My biggest complaint is that it didn't have a lot of information on positioning. Playing on a power play, killing penalties, 2 on 1's, 3 on 2's, etc. Also, I would have liked to have seen instruction on body checking. Overall, this is a good video for those players just starting to play defense and for those who would like to improve their defensive skill.
