he was / is a real head coach, d2 I think, he and I sitemailed a little bit - he gave my son a few tips on how to break into coaching, appears to be a great fellow
he was nice enough to put the time into explaining what 'real life' triangle, motion, flex, and fb and / or whatever else he addressed
his writings have zero to do with the fake game, i.e. HD, other than his own ability to translate real life into HD, which I think he would admit was somewhat limited
