Butch always coached tiger since he was 13 or 14 and butch played on tour, most tour pros have coaches for a 2nd opinion and so the swing stays the same. It's an educated set of eyes. There are players like Lee Trevino who never had a lesson and would say why would I take advice off a guy I can beat, bubba Watson aswellCant help to take that further with your thinking and why did Tiger ever goto a coach, for example Butch Harmon....Tiger is a far better golfer than Butch and Butch can not do what Tiger can do, so how can Tiger have learnt anything from Butch?
