Don't get me wrong, I do like him and half benefitted from one or two of his instructional videos. I wouldn't take his advice on chipping though. ?He isn't a teaching pro any more but, even if he was, he is "pretty good"! Certainly better than most players.
A swing coach is good at analysing and communicating. The pros all have coaches but they're not looking for someone who is a better player than they are. They're looking for someone that understands the mechanics of a golf swing and can identify and fix weaknesses.
