As Sam notes, Freddie has been involved with a lot of us. Add in Paul Cowley somewhere in NC, if you will. I recall hearing of that course from our client, who had previously hired Freddie with them. I don't know what the current situation is, but there was a time when Couples put his name on many projects, regardless of architect.
Heck I co-designed a course with him, never met him, talked on the phone, etc. He was a name only. (and frankly, that is the way our owner wanted it) He even admitted on local TV during a tournament visit that if you gave him a rental car and GPS, he probably still couldn't find the course he designed.
