Based on the USPGA's max-out philosophy used in their PGA Championship set-ups (Atlanta AC added 150 yards to 7213, Hazeltine added 210 yards to 7360, Oak Hill grew 235 yards to 7134, Whistling Straits grew at first 70 yards, then an additional 250 yards, before settling on a growth of 220 total from the original construction), Kiawah could end up with the following yardage set-up for 2012 easily--the tees already exist for such a purpose. Also remember the course played at 7303 for the 1991 Ryder Cup.
