"Would it be more accurate to call him the father of the excessive use of the one dimensional aerial game?"
I just don't think one can say this about William Flynn or his architecture at all. He never wrote or said anything like this and his architecture just doesn't show that at all. Flynn was a great advocate of the ground game as an option! Don't anybody try to point to some hole of Flynn's where you absolutely had to fly the ball onto the green because that doesn't prove a thing about the aerial game in architecture. Every single architect I've almost ever heard of who was any good at the art had some holes like that. That was nothing more than variety. Look at Merion, Cypress, Oakmont, Pine Valley, NGLA, any of the old great ones way before aerial game dominance and you can see this.
