Whether it is the most coveted or not, for a pure GCA, not a former Pro, this commission is above the fold obituary material, IMHO. While I wouldn't think this would be the capstone to a career, none-the-less, the as Tom pointed out, the Olympic brand is universally strong, and Gil has their imprimatur now.
As I'm sure all of you know, explaining GCA to casual acquaintances is an exercise in Boorishness. Finding shorthands to tie in our love of GCA to their world is helpful, if nothing else to keep the boorish outbursts brief. In the real world, someone who has been selected as the _______ architect to design the Olympic _________ venue is immediately recognized as a person of achievement. That halo will never leave Gil, and to the extent it creates an avenue to make GCA more relevant to those not smitten, we should use it, and Gil, and his work, and like work, as a touch point of relevance.
