In summary, I think he is the "leader of the pack" of the generation that is following Coore/Crenshaw/Doak/ Hanse (listed in alpha order).
Although I agree with the premise that Andrew Green's work on the courses you've mentioned is truly superb, your "leader of the pack" comment is far from accurate and mostly absurd.
Work by the likes of Brian Schneider, Mike DeVries, King & Collins, Kye Goalby, Jackson & Kahn, Kyle Franz, Beau Welling, Keith Rhebb, Riley Johns, etc., Mike's Nuzzo and Young are all equal to the caliber and quality of Andrew Green. The golf architecture world is lucky to have such talent-laden group of successors to rely on. Perhaps you ought to find a way to examine more closely the work these folks are presenting than simply doing a "hit and run" along your way to next box on the spreadsheet?
