The original 18 at Trophy Club had Hogan's attention and input. He left the project well before it was completed, reportedly over design and compatibility issues with the developer. According to a former associate who spoke with Hogan on several occasions, it was not a subject that he would discuss.
The course itself is underwhelming, fairly plain tee to green, with some interest on and around the putting surfaces. If it is true that professional golfers turned architects design on the basis of their games, this course is the opposite of what would be expected from Hogan.
The housing development that encompasses the course has had financial problems at different times throughout its history. A longtime mayor of Trophy Club (the city) was a friend of mine and it seemed like he was always putting out small fires (of the political variety). Despite being surrounded by houses, the site of the original course is pretty good as is the routing. I suspect that this is where Hogan had some impact.
BTW, this thread has been addressed here a couple of times previously, so more inforamtion may be available.
