You are right about the green size at No.16,it has shrunk by at least five feet. I am not sure what tournament it was that was held there, it may have been the '77 PGA, but the powers that be, brought the left hand rough in more than usual, to offset the effects of a drought. This forced players to either fade the ball or keep it close to the bunker on the right, whatever shot was played made the hole infinitely more interesting and harder.
