Actually,
I was at the Nike Pittsburgh clinic a couple weeks ago and Dick Bennett gave a pretty good lecture about his defense. I would buy that video. However, the other coaches that I knew at the conference...one of those coaches went to the New York State championship this past year, said that they love that defense. WIth this defense there is a big emphasis on helping, yet your positioning does not stress recovering because you are already in a position to recover.
My friend who went to the NYS championship shifted to that defense this year and kept teams around 54 points a game.
Yet, to answer your question...I did not see the video that is on the market, yet I would definitely do some research on it.
take care
