He's clearly an amazing coach given what his students have achieved and clearly knows a lot more about grappling than i ever will but that's not the same thing as being a good teacher.
Based on the couple of instructionals of his i have i'd say there's plenty of guys like Hall, Schreiner, MacKenzie, Terra, Giles etc. who seem to be far better able to convey complex information related to grappling in a clearer and far more concise manner on video. As i mentioned, all the very smart folks i met studying philosophy in college used very simple language to easily and quickly explain hugely complicated ideas so anyone could understand them in stark contrast to what Danaher does with far simpler ones related to BJJ.
Between the overly verbose teaching style, the rashguards and the Japanese words it all feels a little like try-hard to me; more about cultivating an image than anything else.
