I think the key here is what is good. None of these courses are top 200ish. Yet, most of them are fun well done courses. His work is rarely bad, just not spectacular. To me GCA is about all golf courses and architecture. But we should and do focus on the best of work and not just ok work.
A pretty solid take, although I do think there is merit in discussing the "good" as opposed to the "great" because not many of us get to play "great" on a regular basis.
