USGA had an impassioned speech yesterday at the USOpen calling for better controls on equipment.Ross has many still iconic designs such as Inverness Country Club. He also designed many courses that were used for US Open between 1913 and the mid-1930s - Ross designs hosted like half of the US Opens during this period. Courses like the Newport Country Club in Newport, RI that were extremely difficult in their day but fell out of the US Open rotation because they simply became too short for the advancements made in equipment and the clubs were land constrained and could not be redesigned and lengthened.
The other thing that has happened through time, is that many original designs have been softened primarily by widening the fairway and the first cut of rough.... and decreasing the length of the primary rough such that your average weekend golfer can advance the ball from it.
