Interesting video. The guy makes some valid points, however, his manerism and language make him sound like a person who has not been around for long enough to actually experience a really good techique applied by someone who really knew what he was doing.
I can understand how you feel as he is fairly opinionated and somewhat critical of some practices, which would tend to lead you to believe that he may not understand things.
That said, he is in line with what I preach to my guys concerning effectiveness. I have never worked with him, but he has a good reputation for being able to walk the talk.
No issues from my end!
